WebNov 10, 2024 · Recall that the area of a circle is A = πr2. When measuring angles in radians, 360 degrees is equal to 2π radians. Therefore a fraction of a circle can be measured by the central angle θ. The fraction of the circle is given by θ 2π, so the area of the sector is this fraction multiplied by the total area: A = ( θ 2π)πr2 = 1 2θr2.
