Question

The formula for the volume of a sphere is apower function:What is the domain of the function in thissituation?All real numbersO r>_ 0Or<_ 0

Answer 1

r>=0

Explanation:

The volume of the sphere is given by:

`V=(4\pi r^3)/(3)`

The domain is given by all possible input values of r, which is the radius.

Radius is the length of a segment on the sphere, which can never be negative.

So the domain is r>=0
