Question

3. The surface area of the sphere is 30 m2. Find the radius of the sphere.​

Answer 1

Explanation:

The formula for the surface area is A = 4πr². This formula can be solved for r² and then the result solved for the radius, r:

A

r² = -------- The radius of the sphere is as follows:

4π

√(30 m²)

-------------- meters

2√π
