Find the circumference and the area of a circle with radius 3 m
Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.

Answers

Answer:

The area: 28.26m^2, the circumference: 18.85m

Step-by-step explanation:

The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.

Answer:

Area of a circle= π[tex]r^{2}[/tex]

3.14 x [tex]3^{2}[/tex] = 18.84

The area of the circle is 18.84 [tex]m^{2}[/tex]

Circumference of a circle = 2πr

2 x 3.14 x 3 = 18.84

The circumference of the circle is 18.84 m

They are both the same number but the area is squared.

Maria is making a gelatin dessert for a party. She plans on making 12 servings for every 6 people. If each pan Maria uses to make the dessert holds 8 servings, what is the minimum number of these pans will she needs in order to serve 112 people?

Please I really need help.

Answers

Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!

Answers

Descends 0.55 miles per minute
Answer:
in order to find the answer you have to divide 0.44 by 0.8
when you divide decimals, the number that goes outside needs to be a whole number so it has to be 8
since you moved the decimal you also have to move the decimal from the inside. If you move the decimal it is going to be 4.4
so now you divide those numbers. 4.4/8

How would I find the range btw im only allowed a Ti-84 calculator So pls tell me how to solve this without using any stepbystep caulculators or desmos

Answers

Answer:

D

Step-by-step explanation:

u dont really need a calculator for this problem

to find the answer, you have to look at the equation.

f(x)=20x+4

the 4 is the y-intercept (0,4), which tells us that the range will start from number 4.

the 20x tells u to multiply the x by the 20

so if it was 20(1)=20, 20(2)= 40, 20(3)= 60 ....

so if you add x amount of plates to the barbell, it will be 20 times x plus 4(because 4lbs is the weight of the barbell itself)

so 0 plates is 4, 1 plate is 20(2) + 4 = 44, 20(4)+4= 84 ....

(i didnt do 20(1) or 20(3) because you need to have a even number of plates of each side of the barbell.)

-10 ≤ 2(2x + 7) ≤ 10.

Answers

Answer:

Step-by-step explanation: So first I changed 2(2x + 7) with the distributive property:

4x + 14

Since the above has to be less than or equal to 10, I know that x has to be negative.

If we make x = -1, 4x + 14 simplifies to -4 + 14, which simplifies to 10.

This satisfies the inequality, since it is greater than or equal to -10, and less than or equal to -10.

Hope this explained it well!

Answer:

-6 ≤ x ≤ -1.

Step-by-step explanation:

-10 ≤ 2(2x + 7) ≤ 10

Split it up into 2 inequalities:

2(2x + 7) ≥ -10    (reading from the middle to the left)

4x + 14  ≥ -10

4x  ≥ -24

x  ≥ -6.

and:

2(2x + 7) ≤ 10

4x + 14 ≤ 10

4x ≤ -4

x ≤ -1.

Combining the 2 we have:

-6 ≤ x ≤ -1.
