A cylinder is a geometric solid that is very common in everyday life, such as a soup can. If you take the cylinder apart you find it has two ends, called bases, which are usually circular.

Right circular cylinder:

Definition: A right circular cylinder is a three-dimensional object with two congruent circles as parallel bases and a lateral surface consisting of a rectangle.

Base and side: The bases of right circular cylinder are always congruent and parallel to each other. If you were to 'unroll' the cylinder you would find the side is actually a rectangle when flattened out.

Height: The height h is the perpendicular distance between the bases.

Radius: The radius r of a cylinder is the radius of a base.

Circumference: The circumference of a circle is the distance around it. Here the circumference is denoted by l.
