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