Answer:
86 in. squared
Step-by-step explanation:
The diameter (double the radius) will be the height of the square (20 inches)
So the area of the square is 400 in. squared.
Now find the area of the circle and subtract it from the original square
p is approximately 3.14, times radius squared, which is 100, so
314 in. squared.
400 - 314 = 86
