Circumference divided by radius equals
WebThis brings us to our new angle measure. One radian is the measure of a central angle of a circle that intercepts an arc equal in length to the radius of that circle. A central angle is an angle formed at the center of a circle by two radii. Because the total circumference equals [latex]2\pi [/latex] times the radius, a full circular rotation is [latex]2\pi [/latex] radians.
