Question

Find the area of the circle.


diameter=8 inches

Answer 1

Area = 32 π in^2

Explanation:

Area of the Circle : Area = 2 *π * r^2

diameter = 2 *radius

8 inches = 2 * radius

radius = 8 in/2 = 4 in

radius = 4 in

Area = 2 *π * r^2

Area = 2 *π * (4 in)^2

Area = 2 *π * 16 in^2

Area = 32 π in^2
