WebMeasuring angles in radians enables us to write down quite simple formulas for the arc length of part of a circle and the area of a sector of a circle. In any circle of radius \(r\), the ratio of the arc length \(\ell\) to the circumference equals the ratio of the angle \(\theta\) subtended by the arc at the centre and the angle in one revolution.
