WebDec 17, 2024 · As a length. The length of an arc is directly proportional to the circumference of the circle and is dependent on both the central angle and the radius of the circle. If you think back to geometry, you may remember that the formula for the circumference of a circle is with r representing the radius. Also recall that a circle has 360 degrees. WebThe definition of an angle that measures 1 radians is that the arc that subtends (lies across from) said angle has to measure 1 radius. If the arc length across from an angle is less than 1 radius long, then the angle is less than 1 radians. If the arc length is longer than 1 radius, than the angle is more than 1 radians.
