Webb10 mars 2024 · Circumference is the perimeter of a circle. Since a circle doesn’t have any straight lines, the method for figuring out its perimeter is a little bit different. It involves using Pi and the radius or diameter of the entire shape. [2] You can’t find the perimeter of a circle just by measuring it; you have to use the circumference equation. 3 Webb1 dec. 2024 · Divide the circle's perimeter, also known as the circumference, by pi (3.14159265) to get the diameter of the circle. For example, say you have a circle with a circumference of 40 inches. Work out. 40 ÷ 3.14159265 = 12.732. Divide the diameter by 2 to give you the length of the radius.
