## How do I find the circumference of a cylinder? Circumference of a cylinder formula

Let's start from the beginning - what is circumference? The circumference is a linear distance around the edge of a circle or ellipse. Since a cylinder's cross-section is a circle, you can calculate the circumference of a cylinder using the following formula:

cylinder_circumference = 2 * π * cylinder_radius

or

cylinder_circumference = π * cylinder_diameter

Let's put the formula for the circumference of a cylinder in perspective. Suppose the radius of a cylinder is 5 cm. To calculate the circumference of a cylinder, you have to multiply five by two and by pi, which equals approximately 31.41 cm.
