Question

The surface area of a sphere having a diameter of 8 inches is

Answer 1

64 π inches^2 or 201.06 inches^2 to the nearest hundredth.

Explanation:

The radius = 1/2 * the diameter

= 1/2 * 8

= 4 inches.

The surface area = 4 π r^2

4 π 4^2

= 64 π inches^2

or 201.06 inches^2 to the nearest hundredth.
