Hands-on math!


A cylinder is a solid (3-dimensional object) with circular ends and straight sides.
A pipe is a cylinder. The formula for the volume of a cylinder is:
V = L R2

where R is the radius of the end of the cylinder and L is it's length.
If you think about it, the area of the circular end of the cylinder is just R2, so the volume of the cylinder is just its length times this circular area.

Now, here's a problem for you:
What is the volume of this soup can?
Leave your answer in terms of π

Volume = ________ π cu. in.
