While it makes me look good in answering such questions, Google is a good source, nowadays, to get such answers. Can't claim the credit, as I got this from Google.

A cylinder with radius r units and height h units has a volume of V cubic units given by

V = (pi)r²h

I like to think of the volume of any right angled (meaning the sides go straight up rather than slanted up) solid geometric shape in this way:

You have a flat two dimensional shape - in this case a circle. Two dimensions have area. When we imagine raising this base to some height, we can see it as creating a three-dimensional shape that has volume.

So the measure of the volume is the original area of the base, times the height to which it was raised. I think that visually picturing this would make it easier to remember, as opposed to having to memorize yet another abstract formula.

The volume of a cylinder equals the (area of the base)*height = ? r2 h
