Question

Write the formula for the area of a sector of angle θ (in degrees) of a circle of radius r.

Answer 1

Answer:

The formula for the area of the sector of a circle, A is (θ/360) × πr².

Step-by-step explanation:

Given :  

Let radius of the circle be ‘r’ and angle subtended at the centre of the circle be ‘θ’ .

Area of the sector of a circle, A = (θ/360) × πr²

Hence, the formula for the area of the sector of a circle, A is (θ/360) × πr².

★★ If θ = 180° , then sector becomes a  semicircular region and its area is ½ πr².

★★ If θ = 90° , then sector becomes a quadrant of a circle and its area is ¼ πr².
