Answer:
The correct answer option is: the volume of the basketball when the radius is r.
Explanation:
V(r) represents the volume of the basketball when its radius is r. So for any value for the radius of the basketball, its volume is going to vary accordingly.
Hence, we can say that the function V(r) is dependent on the variable r which is the radius of the basketball. Therefore, by putting in different values of r, we can find the corresponding value of the volume of the basketball.
