Answer

Answer:

B. the volume of the rubber ball when the radius equals $\frac{5}{7}$ feet

Explanation:

Step1: Recall function notation

For a function $V(r)$, $r$ is the input (radius in this case) and $V(r)$ is the output (volume).

Step2: Analyze $V(\frac{5}{7})$

Here, $\frac{5}{7}$ is substituted for $r$. So it represents the volume when the radius $r = \frac{5}{7}$ feet.
