7th Grade Math - Circumference of a Circle
Circumference is the measurement of the outer boundary of a geometric figure, especially a circle. In order to calculate the circumference of a circle, you have to use the formula C = 2(pi)r in which C stands for circumference is equal to 2 times the value of pi times the radius. Once you have all of the values, you can simply substitute to find the circumference. In the following video, you will learn in complete detail how to calculate the circumference of a circle using various examples.
