WebThe area of a sector is a fraction of the area of the circle. This area is proportional to the central angle θ. This implies that the bigger the central angle, the larger is the area of the sector. Area of a sector = (θ / 2) × r 2 where r = radius and θ is in radians. or Area of a sector = (θ / 360) × πr 2 where θ is in degrees. WebMar 13, 2024 · Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.
