Answer:

[tex]A_{total} = 217\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the bottom rectangle

[tex]A = l * w[/tex]

[tex]A = 14\ cm * 11\ cm[/tex]

[tex]A = 154\ cm^2[/tex]

Step 2:  Determine the area of the top rectangle

[tex]A = l * w[/tex]

[tex]A = 7\ cm * (20\ cm - 11\ cm)[/tex]

[tex]A = 7\ cm * 9\ cm[/tex]

[tex]A = 63\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 154\ cm^2 + 63\ cm^2[/tex]

[tex]A_{total} = 217\ cm^2[/tex]

Answer:  [tex]A_{total} = 217\ cm^2[/tex]

A circular fountain has 132 feet of railing around it. What is the area of the fountain, Use 3.14 for π.

Answers

Answer:

1387.2 ft² (nearest tenth)

Step-by-step explanation:

Formulae

Circumference of a circle = [tex]2 \pi r[/tex]Area of a circle = [tex]\pi r^2[/tex]

(where r is the radius of the circle)

The railing of the circular fountain is the circumference of a circle.

The area of the fountain is the area of a circle.

First, find the radius by using the circumference formula:

Given:

circumference = 132 ft

[tex]\implies 132=2 \pi r[/tex]

[tex]\implies r=\dfrac{132}{2 \pi}=\dfrac{66}{\pi}[/tex]

Now input the found value of r into the formula for the area of a circle:

[tex]\begin{aligned}\implies \textsf{Area} & =\pi \left(\dfrac{66}{\pi}\right)^2\\\\ & = \dfrac{4356}{\pi}\\\\ & = \dfrac{4356}{3.14}\\\\ & = 1387.261146...\\\\ & = 1387.3 \: \sf ft^2\:(nearest\:tenth)\end{aligned}[/tex]

Undefined

Solution:Notice that the x-coordinates of the points that the line intersects are the same.If the x-coordinates are the same, then the slope is undefined.If the slope is undefined, then the line's run is equal to 0 units.Remember the slope formula: Rise/RunRise - how many units we move up or downRun - how many units we move left or rightIf the run is zero, then we basically divide by zero, which we can't do.

A square is circumscribed about a circle with a diameter of 10 cm. What is the correct set up to find the area of the shaded region?

Answers

Answer:

21.5 cm² (nearest tenth)

Step-by-step explanation:

FormulaeArea of a square = x² (where x is the side length)Area of a circle = πr²  (where r is the radius)Radius = 1/2 diameter

Solution

To find the shaded region, subtract the area of the circle from the area of the square.

Square

Area of the square = 10² = 100 cm²

Circle

Given diameter of circle = 10 cm

⇒ radius = 10 ÷ 2 = 5 cm

⇒ Area of the circle = π · 5² = 25π cm²

Area of shaded region

= area of square - area of circle

= 100 - 25π

= 21.46018366...

= 21.5 cm² (nearest tenth)

Answers

Answer:

8 cubic meters

Step-by-step explanation:

Formula for the volume of a rectangular pyramid:

[tex]V=\frac{lwh}{3}[/tex]

Take note

[tex]l=[/tex] base length

[tex]w=[/tex] base width

[tex]h=[/tex] pyramid height

We are given [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex].

Lets solve for [tex]V[/tex]

[tex]l=3[/tex]

[tex]w=2[/tex]

[tex]h=4[/tex]

Now plug in our numbers into the formula:

[tex]V=\frac{3*2*4}{3}[/tex]

Evaluate the numerator

[tex]3*2*4=24[/tex]

Then we have

[tex]V=\frac{24}{3}[/tex]

What shape is created by the rotation and what is the approximate circumference of the base? circumference of a circle: c = 2πr a cylinder with a circumference of about 63 mm a cylinder with a circumference of about 126 mm a cone with a base circumference of about 63 mm a cone with a base circumference of about 126 mm

Answers

The triangle is rotated about an axis then it creates a cone and the approximate circumference of the base is 63 mm. Then the correct option is C.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The equilateral triangle shown is rotated about line a.

Each side of the triangle measures 20 mm.

If the triangle is rotated about an axis then it creates a cone.

Then the radius of the cone will be

[tex]\rm r = \dfrac{20}{2} = 10 \ mm[/tex]

Then the height of the cone will be

[tex]\rm h = 20 \sin 60^o\\\\h = 17.32 \ mm[/tex]

Then the circumference of the base circle will be given as

[tex]\rm Circumference = 2 \pi r\\\\Circumference = 2 \pi \times 10\\\\Circumference = 62.8318 \approx 63 \ mm[/tex]

If you invest $200 at an interest rate of 10%, how much money will you have after three years?

Answers

Well, if it’s just an interest rate of 10% then you would have $220 if you have an interest rate of 10%.


If it’s an annual interest rate (yearly interest rate), then you would have $266.20

1st year: $200 x 1.10 = $220
2nd year: $220 x 1.10 = $242
3rd year: $242 x 1.10 = $266.20

What is the perimeter of a shape?

Answers

Perimeter is the combined ammount of all the sides added together.

For example, if a square has sides of 4, it would be 16 because 4+4+4+4 = 16 units.

Answer:

Perimeter is the total distance around the outside of a shape.

Step-by-step explanation:

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter.

What is Division?

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The total filling that was available with Camilo is 32 ounces, which he put in three different trays equally. Therefore, the filling available in each tray is equal to,

[tex]\rm \text{Filling in each tray} = \dfrac{\text{Total Filling}}{\text{Number of tray}}\\\\\text{Filling in each tray} = \dfrac{32\ ounces}{3} = 10.667 ounces[/tex]

Either enter an exact answer in terms of piπpi or use 3.14 for piπpi and enter your answer as a decimal.

Answers

Answer:

64π or 200.96

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex]. The radius of the circle is half the diameter, which is 16/2 = 8. The area of the circle is 64π.

Answer:

64π = area
200.96 = area

Step-by-step explanation:

Diameter = radius * 2

16 = 2r

radius = 8

Radius^2 * π = area

8^2 * π = area

64π = area

64*3.14 = area

200.96 = area
