The function (n) =

r2 can be used to find the volume of air inside a basketball given its radius. What does V (r)

represent?

see the explanation

Step-by-step explanation:

The correct question is

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

In this problem

The radius r represent the independent variable or input vale

The volume V represent the dependent variable or output value

so

V (r) represent the volume of air inside a basketball with radius r
