Question

A sphere has a diameter of 14.5 inches. What is the surface area of the sphere? 841π in² 420.5π in² 210.25π in² 105.125π in²

Answer 1

210.25 pi in^2.

Explanation:

Diameter = 14.5 inches so the radius = 1/2 * 14.5 = 7.25 inches.

So the surface area of the sphere = 4 pi r^2

= 4 * pi * 7.25^2

= 210.25 pi in^2.
