Question

Please someone help ASAP! :)

Answer 1

236.625

Explanation:

2 semi circles = 1 circle

Radius = 15/2 = 7.5

Circle + Rectangle

(3.14 × 7.5²) + (15 × 4)

236.625 ft²

Answer 2

236.715 ft squared

Explanation:

This figure is composed of a rectangle and two semicircles that we can just combine into one circle. Let's find the areas separately.

Circle: the two semicircles will just add up to a circle, so we'll find the area of a circle with radius 15/2 ft.

`A=\pi r^2=\pi *(15/2)^2=56.25\pi` ≈
`176.715` ft squared

Rectangle: the area of a rectangle is length times width; here the length is 15 and the width is 4, so A = 15 * 4 = 60 ft squared.

Now, we just add these two together:

176.715 + 60 = 236.715 ft squared

Hope this helps!
