In this video, we learn how to solve the circumference of a circle. First, you will need to find the radius. For an example, let's say the radius is 5 inches. After you find this, you need to multiply this number by two to find the diameter. Next, take this number and multiply it by pi (3.14). When this is done with, you will write down what the circumference is and make sure not to forget to write the units next to it. This is a very simple equation to figure out, so don't hesitate to learn how to do it!
