Use the formula for the volume of a cylinder.

Volume of a cylinder = ╥ r² h
We need the radius which is 1/2 of the diameter.
Well, what is 1/2 of 9? It is 4.5, right? That is our radius.
V = ╥ (4.5cm)² (20cm)
V = ╥ (20.25cm)(20cm)
V = ╥ (405cm)^3
Answer: V = 405╥(cm)^3
Remember that volume is measured in cubic units.
