5-2: Surface Areas of Cylinders

Part 1


Parts of a Cylinder

A cylinder is a three-dimensional figure with two circular bases that are the same size.

A base of a cylinder is one of a pair of parallel circular faces that are the same size.

The height of a cylinder is the length of a perpendicular segment that joins the planes of the bases. In a right cylinder, a segment representing the height joins the centers of the bases. In this Topic, you may assume that all cylinders are right cylinders unless otherwise noted.

The lateral surface of a cylinder is the curved surface not included in the bases.
