3 Ways to Calculate the Circumference of a Circle - wikiHow

WebFind the radius, diameter, and circumference of each circle. Radius = 4 inches (Remember the radius goes halfway across the circle.) The diameter is always twice as long as the radius. So, the diameter will be: 4 x 2 = 8 The diameter is 8 inches. For the circumference, we need to choose a formula. WebTo calculate the length (= the arc length) you need to calculate the whole circumference first and then multiply it by 3/4 to find the length you really want: Whole circumference = 2*Pi*radius = 8*Pi = approx. 25.13dm, The length that you need: (8*Pi) * (3/4 ) = 6*Pi = approx. 18.85dm.
