If you measure the distance across (the diameter) with a piece of string, then wrap that same string around the edge (the circumference) and count how many diameters fit, you’ll find it takes a little more than 3 lengths of the diameter — about 3.14 of them.
This is true for every circle (CD, button, dartboard): circumference = π × diameter, and π ≈ 3.1416 (often approximated as 22/7). So the circumference is about 3.14 times the diameter.
Quick measuring tips: wrap the string snugly around the circle for the circumference, mark the string, then lay it alongside the diameter-lengths and count — you should get about 3 full diameters plus a small extra (~0.14 of a diameter).
