    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).
