This video explains how to find the circumference of a circle. In order to find a circle's circumference, you must know one of two things. The radius, which is the distance from the middle of the circle to the edge, or the diameter, which is the distance from edge to edge. Two formulas are given, one using the radius and one using the diameter, with both of them using pi, which equals 3.14. These formulas are then applied to find the circumferences of two different circles. This video can help you solve math or geometry problems that deal with finding the circumferences of circles.
