whpalmer4 · Answer

volume of a cylinder is given by $$V = \pi r^2 h$$You know $r$ and $h$ from the diagram.  Do the calculation...

rebeccapink6398 · Answer

No I don't know :(

whpalmer4 · Answer

You have two dimensions marked on the diagram.  One is the height, and one is the radius.

whpalmer4 · Answer

A radius goes from the center of a circle, to the edge.  It is half the length of a diameter.

I hope I don't need to explain height to you :-)
