A cylinder is a uniform solid with two opposing circular
faces. The surface area between the faces is the lateral area.
This lateral surface area of a cylinder is equal to the circumference
of the cylinder times the distance between the faces.
To find the volume of a cylinder, find the area of one of its
circular faces, and multiply it by the distance between the faces.
Task: If a cylinder has a radius of 8, and the
distance between its circular faces is 20, what is its volume?
Volume = 1280Π
The volume is the area of one circular face
times the distance between the circular faces. The area of the face
is 
times
8 squared, so we have 
.
