Answer: 15.45133224
Step-by-step explanation:
Find the area of the half circle.
r=6
pi (6)^2/2
Divide by two because it is a half circle not a circle.
pi (6)^2/2=18 Pi
We know there are two square with even side lengths so we know the sides of the two squares are 6 it is the same as the radius of the circle.
We multiply B*H= Area of the square
6*6=36 is the length of half of the rectangle aka the square
So we multiply that by 2 because there are 2 squares so we get 72
72-18 Pi= 15.45133224
