Question

What is the radius of a sphere whose surface area is 100 square centimeters?

Use the formula for determining the surface area of a sphere, S = 40, and
3.14 for 1. Round your answer to the nearest hundredth.​

Answer 1

Explanation:

The formula for determining the surface area of a sphere is expressed as

Surface area = 4πr^2

Where

r represents the radius of the sphere

π is a constant whose value is 3.14

From the information given,

Surface area of the sphere = 100 centimeters ^2. Therefore,

100 = 4 × 3.14 × r^2

100 = 12.65r^2

r^2 = 100/12.65 = 7.9051

r = √7.9051

r = 2.81 centimeters
