Right circular cylinder

To make a right circular cylinder of given height and circumference of base.

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.

**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**.
