In order to determine the circumference of the circle, we must be familiarized with its equation.

C = 2 pi r

C = Circumference

r = radius

Hence to find for the circumference, we must first determine the radius of the circle.

Example:

Find the circumference of the circle with a radius of 20 cm.

C = 2 pi r

C = 2 pi (20 cm)

C = 40pi cm

C = 125.66 cm
