Answer 1

The surface area of a sphere that is 8 inches is 201.06in²

Answer 2

Answer:

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

Step-by-step 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.
