Question

The function v(r)= 4/3 can be used to find the volume of air inside a basketball given its radius. What does V(r) represent?

Answer 1

we know that

The function to find the volume of air inside a basketball is equal to find the volume of a sphere

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

where

the variable x is the radius of the basketball

so

For $x=r$

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

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

therefore

the answer is the option B

the volume of the basketball when the radius is r

Answer 2

The volume of the basketball when the radius is r
