Question

The function V(r) = four-thirds pi r cubed can be used to find the volume of air inside a basketball given its radius. What does V(r) represent?

the radius of the basketball when the volume is V
the volume of the basketball when the radius is r
the volume of the basketball when the radius is V
the radius of the basketball when the volume is r

Answer 1

V(r) is the volume of basketball when the radius is r.

Step-by-step explanation:

Given, the function V(r) = $\frac{4}{3}\pi r^{3}$ can be used to find the volume of air inside a basketball given its radius (r).

V(r) represents the volume of the basketball when the radius is r.

Hence, V(r) is the volume of basketball when the radius is r.

Answer 2

Option B is correct answer.

Step-by-step explanation:

Given that

$V (r)= \frac{4}{3} \pi r^{3}$

Means the volume is totally depends on the radius of the basket ball. & volume is changes with the radius.

Thus this function represents the volume of the basketball when radius is r.

Thus option B is correct answer.
