Radians, Arc Length and Area of a Sector - StudyWell

Area of a Sector. When the angle at the centre of a circle is given as θ radians, we can define the area of a sector to be 1 2 r 2 θ, where r is the radius. This also follows from the definition of radians above. Note that the full circle makes an angle of 2 π radians and we have the part of the circumference that subtends from an angle of θ.
