Answer: 81 π.
Step-by-step explanation: To find the area of a circle, you need to multiply the circle's radius squared by pi. However, this problem is in terms of pi, so we're just going to find the radius squared. We're given the diameter, but we can simply cut it in half since the radius is half the diameter. The diameter for this circle is 18, so divide 18 by 2, and 9 is your radius. 9^2 is 81, so 81 π is your answer in terms of pi because when you find the radius squared, you put pi next to it.
Have a great day! :)
Answer: the area is 81π
Step-by-step explanation:
The formula is A=πr
^{2}
The raidius would be 9 (18/2)

Find the surface area of the figure. Be sure to show all of your work and steps in solving for your answer.
Answer:
The surface area of a figure is the sum of all the sides that consist of it.
Let's first find the base's area, using the formula for the area of a rectangle, L · W:
9(6)
= 54 is the area of the base.
Now let's find the entire front side of this figure's area and double it so we get both the areas of the front and back side (using the formula for the area of a rectangle):
4(9)[bottom front rectangle] + 4(5)[upper front rectangle]
36 + 20
= 56, now double that area to get the area of both the front and back side:
56(2)
= 112 is the area of both the entire front and back side of this figure.
Now let's figure out the area of the right whole side of this figure then double it so we get both the areas for the left and right sides.
But, if we look at the middle rectangle to the right and left sides, we can see that there is no value, so let's find the value first.
The total length across the figure is 9 inches.
And we are given that the rectangle above intersects with the total length, so let's exclude that from 9 inches.
9 - 4 = 5, so now the total length of the two rectangles beside the above rectangle is 5.
But we want to find the value of one side, so divide 5 by 2.
5/2 = 2.5 inches.
Now let's find the whole entire area of the right side to this figure.
5(6)[upper right rectangle] + 2.5(5)[flat middle right rectangle] + 6(4)[bottom right rectangle)
30 + 12.5 + 24
= 66.5, now double that area to get both the area of the right and left side.
66.5(2)
= 133, is the area of both the right and left side of this entire figure.
Finally, we add all those areas together to get the surface area:-
54 + 112 + 133
= 299 inches is the surface area for this figure.
Answer:The surface area of a figure is the sum of all the sides that consist of it.
Let's first find the base's area, using the formula for the area of a rectangle, L · W:

36 + 20
= 56, now double that area to get the area of both the front and back side:
56(2)
= 112 is the area of both the entire front and back side of this figure.
Now let's figure out the area of the right whole side of this figure then double it so we get both the areas for the left and right sides.
But, if we look at the middle rectangle to the right and left sides, we can see that there is no value, so let's find the value first.
The total length across the figure is 9 inches.
And we are given that the rectangle above intersects with the total length, so let's exclude that from 9 inches.
9 - 4 = 5, so now the total length of the two rectangles beside the above rectangle is 5.
But we want to find the value of one side, so divide 5 by 2.
5/2 = 2.5 inches.
Now let's find the whole entire area of the right side to this figure.
5(6)[upper right rectangle] + 2.5(5)[flat middle right rectangle] + 6(4)[bottom right rectangle)
30 + 12.5 + 24
= 66.5, now double that area to get both the area of the right and left side.
66.5(2)
= 133, is the area of both the right and left side of this entire figure.
Finally, we add all those areas together to get the surface area:-
54 + 112 + 133
= 299 inches is the surface area for this figure.

Answer:

Answer: 24
Explanation: 12+40 is 52, perimeter is adding up all the sides. since perimeter is 100, then you have to see what numbers you add to get 100. 100-52 is 48. since there are 2 sides, you divide 48 by 2, which is 24.

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
We're given that:
Time spent by Vlad on history homework = 20 minutesTime spent by Vlad on math homework (x math problems) = 2 minutes on each problemy = time he spent on doing overall homeworkThen we have:
y = time on math homework + history homework
y = 2 +2 +2 ... (x times) + 20 minutes
[tex]y = 2x + 20[/tex]
x is "number of math problems". Thus, x can be 0,1,2,... These numbers are called non-negative integers(or integers greater or equal to 0) or whole numbers.
y is the time taken, but we see that
y = 2 times (non-negative integer) + 20
y = positive integer times non-negative integer + positive integer
Thus, we have:
y = non-negative integer + positive integer = positive integer
Thus, y assumes positive integral values only (in minutes).
Also, y is always going to be at least 20 (as history homework is going to take 20 minutes, even if math homework is nill ).
Thus, the expression for y is y = 2x +20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20

Which function is graphed on the right? y = 2x 3 – 2 y = 2x–3 2 y = 2x–2 3 y = 2x–2 – 3
The equation of the function which is graphed on the right is specified by: Option C: y = 2^{x-2} + 3
How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
Since there is no graph available, we will work with the image attached below.
The function, as visible is tending to output 3 and x goes more and more negative.
That means:
[tex]\lim_{x\rightarrow -\infty}f(x) = 3[/tex] (assuming the predicted pattern is true).
Checking this for all the options:
Case 1: [tex]y = f(x) = 2^{x+3} - 2[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x+3} -2 = -2[/tex]
Thus, the graph doesn't belong to this function.
Case 2: [tex]y = f(x) = 2^{x-3} + 2[/tex]
[tex]\lim_{x\rightarrow -\infty} f(x) = \lim_{x\rightarrow -\infty}2^{x-3} + 2 = 2[/tex]
Thus, the graph doesn't belong to this function.
Case 3: [tex]y = f(x) = 2^{x-2} +3[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x-2} +3 = 3[/tex]
Thus, the graph may belong to this function. (we are still not sure since the last option may also have same limit, which if is found to be true, then additional findings would've to be done too).
Case 4: [tex]y = f(x) = 2^{x-2} - 3[/tex]
[tex]\lim_{x\rightarrow -\infty}f(x) = \lim_{x\rightarrow -\infty} 2^{x-2} -3 = -3[/tex]
Thus, the graph doesn't belong to this function.
Thus, assuming at least one option is true, the graph of the considered function on the right is of the function [tex]y = f(x) = 2^{x-2} +3[/tex]

Alex is 12 years older than George.
Carl is three times older than Alex
The sum of their ages is 68
Find the ratio of George's age to Carl's age to Alex's age.
Answer:
George : Carl : Alex = 1 : 12 : 4
Step-by-step explanation:
let a = Alex's age in years
let g = George's age in years
let c = Carl's age in years
Given:
Alex is 12 years older than George⇒ a = 12 + g
⇒ g = a - 12
Given:
Carl is three times older than Alex⇒ c = 3a
Given:
The sum of their ages is 68⇒ a + g + c = 68
Substitute the first two equations in the last equation and solve for a:
⇒ a + (a - 12) + 3a = 68
⇒ 5a - 12 = 68
⇒ 5a = 80
⇒ a = 16
Substitute the found value of a into the other equations to find g and c:
⇒ g = 16 - 12 = 4
⇒ c = 3(16) = 48
Therefore:
Alex = 16 years oldGeorge = 4 years oldCarl = 48 years oldRatio
George : Carl : Alex = 4 : 48 : 16
Reduce by dividing by 4 → 1 : 12 : 4
