This calculator calculates for the radius, length, width or chord, height or sagitta, apothem, angle, and area of an arc or circle segment given any two inputs. We know that for the angle equal to 360 degrees (2), the arc length is equal to circumference. arc length (s) = radius (r) central angle () Thus, the length of an arc is equal to the radius r of the sector times the central angle in radians. . Examples - Calculations with Radians. Then go to the apex of where you want the arch, at the highest point in the middle and lower your string straight down. Arc length is equal to the product of the radius and the central angle in radians. Simply input any two values into the appropriate boxes and watch it conducting all calculations for you. Divide the chord length by double the radius. Now we just need to find that circumference. Multiply the radius by the central angle to get the arc length. degree. If the angle of the arc is , then you can relate /2 with R and B by the equation. It is a measure of the 'height' of the arc.
