The volume of a cylinder is [tex] \pi [/tex]r^2h. Using the actual value of pi, let's set up an equation by filling in the variables.

[tex] \pi [/tex](12^2)20 = volume of the cylinder

This gets you [tex] \pi [/tex](144 x 20) = [tex] \pi [/tex]2880 in^3

This is your final answer. [tex] \pi [/tex]2880 in^3
