Answer:
25π in²
Step-by-step explanation:
Since each circle has the same area, they'll have the same radius. Therefore, the radius of each circle will be 1/8th the length of the rectangle, or 1/8 * 20 = 2.5 inches.
This means that the area of each circle is A = πr² = π(2.5)² = 6.25π in², making the combined area of the 4 circles equal to 25π in².
Therefore, the shaded area is 25π in².
