Web1st step. All steps. Final answer. Step 1/1. A circle has a total of 360 degrees. The length of an arc is proportional to the ratio of the central angle of the arc to the total degre measure of a circle, 360 degrees. View the full answer. WebOne radian is the angle measure that we turn to travel one radius length around the circumference of a circle. So radians are the constant of proportionality between an arc length and the radius length. It takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the center of a circle.
