If you have the length of the radius and the degree of the angle, calculation of the length of an arc is simple.

First, calculate the circumference of the circle using the radius (C = 2 * pi * r). You can multiply the known circumference by the ratio of the angle to the full circle (i.e. degree of arc/360ยบ). The final product is the length of the arc.
