Complete question is;
The function V(r) = (4/3)πr³ can be used to find the volume of air inside a basketball given its radius. What does V(r) represent?
A) the radius of the basketball when the volume is V
B) the volume of the basketball when the radius is r
C) the volume of the basketball when the radius is V
D) the radius of the basketball when the volume is r
Answer:
B: V(r) is the volume of the basketball when the radius is r.
Explanation:
The function V(r) = (4/3)πr³ means that the volume of air inside the basketball depends on the radius of the basketball.
Now, this means that the radius in this case will be the independent variable while the volume is called the dependent variable.
Thus, V(r) is the volume of the basketball when the radius is r.
