Question

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

Answer 1

V(r) represents the volume of air inside the basketball depends on the radius. Volume is the dependent variable while the radius is the independent variable.

Explanation:

V(r) represents the volume of air inside the basketball depends on the radius. Volume is the dependent variable while the radius is the independent variable.

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

For, example, when r = 7cm

V(7) = 4/3 x 22/7 x 7³

= 1437.33 cm³....
