How to find the Volume of a Cylinder. This page examines the properties of a right circular cylinder. A cylinder has a radius (r) and a height (h) (see picture below). This shape is similar to a soda can. The surface area is the area of the top and bottom circles (which are the same), and the area of the rectangle (label that wraps around the can) Cylinder Volume Formula Practice Problems on Area of a Cylinder
