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. WebFind the area of a sector of a circular region whose central angle is 3 radians with a radius of 5 feet. Solution: The radius of sector $= r = 5$ feet. Angle of sector $= \theta = 3$ radians. If is measured in radians, then. The area of the sector $= \frac{\theta}{2}\times r^2 = \frac{3}{2}\times5^2 =37.5$ sq. feet.
