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. WebWe’ve already said that the perimeter of the shaded region is equal to the circumference of the full circle made up of these four quarter circles. So using the formula 𝐶 equals 𝜋𝑑, we find that the perimeter of the shaded region is 𝜋 multiplied by 68.
