Answer:

A = 3.9 in²

Explanation:

To find the area of the shaded region, you need to find the (1) area of the entire square, then (2) find the area of the 1/2 circles, then (3) subtract them and divide by 2. Because the 1/2 circles are identical, you can combine them and just use the circle area equation.

Area of the Square:

A = l x w

A = 6 in x 6 in

A = 36 in²

Area of Combined 1/2 Circles:

A = πr²

r = 6 in / 2

r = 3 in

A = π(3)²

A = 9π -----> 28.3 in²

Area of Shaded Region:

A = (Area Square - Area Circle) / 2

A = (36 in² - 28.3 in²) / 2

A = 7.7 in² / 2

A = 3.9 in²
