The volume of the cylinder is 90 pi when the radius is 3.

A radius of 3 gives the value 90.

Answer 1

The correct interpretation for the function notation $V(3)=90\pi$ is:

The volume of the cylinder is $90\pi$ when the radius is 3.

This means that when you substitute $r=3$ into the volume formula $V(r)=10\pi r^2$, you find that the volume of the cylinder with a radius of 3 inches is $90\pi$ cubic inches.
