The function V of r is equal to 4 thirds pi r cubed can be used to find the volume of air inside a basketball given its radius. What does V of r represent?

In the function V(r) = (4/3)πr³, r is the input, representing the basketball’s radius, and V(r) is the output, representing its volume. So V(r) means the volume of the basketball when its radius is r. Choice B describes this relationship.
