What is the volume of the sphere?

pav-90 [236]

Answer:

The formula for the volume of a sphere is V = 4/3 πr³.

Step-by-step explanation:

Surface area of sphere = 4πr2

Volume of a sphere = 4/3 πr3

You only need to know the radius to figure both the volume and surface area of a sphere.

Answers for surface area problems should always be in square units.

Answers for volume problems should always be in cubic units.
