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. Each cylinder has a radius and height as you can see in the diagram below.

**Practice** Problems on Area of a Cylinder

##### Problem 1

Use the formula for the volume of a cylinder as shown below.

- Volume = Π *(r)
^{2}(h) - Volume = Π *(2)
^{2}(6)
= 24 Π

##### Problem 2

Use the formula for the volume of a cylinder as shown below.

- Volume = Π *(r)
^{2}(h) - Volume = Π *(3)
^{2}(5)
= 45 Π

##### Problem 3

Use the area of a cylinder formula.

- Volume = Π *(r)
^{2}(h) - Volume = Π *(6)
^{2}(7)
= 252 Π
