WebMar 27, 2024 · Let's look at an example. Suppose you want to find the circumference of a 5 cm diameter circle. These would be the steps to follow: Use the appropriate equation, which, in this case, is the circumference to diameter formula: c = πd.; Input the diameter in the equation: c = π × (5 cm) = 15.708 cm.; That's it. 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.
