A worked example
A cylinder with a radius of 3 and a height of 5 has a volume of about 141.37 cubic units.
Frequently asked questions
Why does a cone's volume formula have a 1/3 in it?
A cone is exactly one-third the volume of a cylinder with the same base radius and height — this comes from a general result in calculus about how the volume of pyramids and cones relates to the prism or cylinder that contains them.
What units will the result be in?
Whatever you entered, cubed — if all measurements are in centimeters, the volume comes out in cubic centimeters.
