Summary
The length of an arc is a portion of the circumference of a circle, and the degree measure of an arc is equal to the measure of the central angle that intercepts the arc. The radian measure of a central angle is defined as the ratio of the length of the arc the angle subtends, s, divided by the radius of the circle, r. To convert degrees to radians, one must multiply the degrees by 1.
