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 radius is 1 m, C = 2 tan-1(2/(2 × (1-1))) = 2 × 90 Using Calculus to find the length of a curve. After entering the central angle of arc (30 degree) and diameter of circle 50, Press “CALCULATE” button and Arc Length Calculator will calculate Arc length on the right side of the calculator in the status block. Can calculate area, arc length,chord length, height and perimeter of circular segment by radius and angle. What is the radius? All suggestions and improvements are welcome. Then, if you multiply the length all the way around the circle (the circle’s circumference) by that fraction, you get the length along the arc. If you talk about the definition of the arc length in simple terms, it is the length of a part of the circumference.
