The area of a circle is pi*r^2
First find the biggest circle's area
then find the little circle's area
Big circle area:
The radius is 8 because on the graph, the small circle's radius is half of the big circle.
(note that this does NOT mean that one small circle is half of the big circle.
3.14*8^2=200.96 ft^2
Small Circle area:
The radius is 4 as shown on the graph
3.14*4^2= 50.24
Remember that there are two of them so the of the 2 small circles would be 100.48 ft^2
Shaded Region:
All you have to do now is to subtract the 2 small circles from the big circle:
200.96-100.48=100.48
