The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . where is circumference and is diameter. You can test this formula at home with a round dinner plate. If you measure the circumference and the diameter of the plate and then divide by , your quotient should come close to .
To find the distance around the circle, you must find the diameter, which is two times the radius. Then you multiply the length of the diameter by Pi. (Pi is a constant roughlâ¦y equal to 3.14).
