Answer:

Area of a sector

In a circle with radius r and centre at O, let ∠POQ = θ (in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. Now the area of the sector for the above figure can be calculated as (1/8) (3.14×r×r).

Answer:

In a circle with centre O and radius r, let OPAQ be a sector and θ (in degrees) be the angle of the sector. Area of the circular region is πr². Let this region be a sector forming an angle of 360° at the centre O. Then, the area of a sector of circle formula is calculated using the unitary method.
