You can calculate it using the formula we mentioned above: CA = l/r, where l is the arc length and r is the radius of the circle. What is an arc length? WebTo use the arc length calculator, simply enter the central angle and the radius into the top two boxes. If we are only given the diameter and not the radius we can enter that instead, though the radius is always half the diameter so it’s not too difficult to calculate. The calculator will then determine the length of the arc. city of elmhurst fence permit
