What is Circumference of a Circle?

Circumference is the distance around the edge of a circle. It is the perimeter of a circle. Example: The circumference of a circle with a radius of 5 cm is 31.4 cm.

This can be calculated using the formula C = 2πr, where r is the radius. Therefore, C = 2π5 = 31.4 cm.
