Question

The radius of a sphere is 22 millimeters. Find its surface area in square centimeters. Round your answer to the nearest hundredth (two decimal places). Use 3.14 to approximate pi.

Answer 1

60.79 square centimeters

Explanation:

The surface area of the sphere is 6,079.04 square millimeters. Since there are 100 square millimeters in a square centimeter, dividing by 100 converts the surface area to 60.79 square centimeters.

Answer 2

Surface area = 4πr² = 4 * 3.14 * 22² = 6082.12
