How to Find the Circumference of a Circle

To find the circumference of a circle, you can use the formula C = 2 * π * r, where C represents the circumference and r represents the radius of the circle. The value of π is approximately 3.14159. Therefore, the formula can also be expressed as C = π * d, where d is the diameter of the circle, and C is the circumference.
