Question

The function can be used to find the volume of air inside a basketball given its radius. What does V(r) represent?

Answer 1

The notation V(r) actually gives the volume of air inside the basketball.

V(r) is volume as a function of radius, r

It can be written as:

V(r) = 4/3πr³

So, for any value of r, we can get the volume V.

For, example, when r = 7cm

we can say;

V(7) = 4/3 x 22/7 x 7³

       = 1437.33 cm³
