If the arc was a full circle, it would have 360 degrees, but because it is not a complete circle we need to know what percent of a circle it is. We do this by diving the angle by the total angle. 120 degrees ÷ 360 degrees = 0.3333 or 33.33% of a full circle. Next we calculate the circumference of the full circle.
