Question

The function v(r)= 4/3 pie r^3 can be used to find the volume of air inside a basketball given its radius. What does V(r) represent ?

Answer 1

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

Here, V(r) is the function dependent on the variable r whch is the radius of any sphere.

By plugging different values of r in the formula. one can find the volume associated with it.

Here, V(r) represents the volume of the sphere when the radius is equal to r.
