The formula for finding the length of an arc on a circle is L=2πr(x360) , where r is the radius of the circle and x is the measure of the central angle of the arc. Solve for x.
The formula for finding the length of an arc on a circle should be L = 2πr (x/360). In this sense, to solve for x we need to isolate x on one side of the equation. So start with multiplying both sides by 360. That would give us 360 L = 2πr (x) Now divide both sides by 2πr: 360L/(2πr) = x Thus, x = 360L/(2πr) .
