What is the area of d=8 and r=4
Alex

So, for the semi circle, we need to find the area of a circle then divide it by 2.

pi times r squared

\pi 16 is the area of a circle with the radius of 4

(I'm going to use 3.14 as pi)

So 3.14 times 16 is 50.24

Divide that by 2 and we get 25.12

For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.

8 times 8 is 64.

To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12

So the area is 89.12 feet squared.
