A cylinder's volume is Ï rÂ² h, and its surface area is 2Ï r h + 2Ï rÂ². Learn how to use these formulas to solve an example problem. A cylinder's volume is Ï rÂ² h, and its surface area is 2Ï r h + 2Ï rÂ². Learn how to use these formulas to solve an example problem. Created by Sal Khan. Let's find the volume of a few more solid figures and then if we have time, we might be able to do some surface area problems.
