࿇ Given :-

➠ Radius of circle ( r ) = 7 cm

➠ Arc subtends an angle at centre ( θ ) = 60°

࿇ Find :-

➠ Area of Sector

࿇ Solution :-

Area of a sector = θ/360∘ × π × r²

➺ 60 ° / 360 ° × 22/ 7 × ( 7 × 7 ) cm ²

➺ 1 / 6 × 22 / 7 × 49 cm ²

➺ 1 / 3 × 11 × 7 cm²

➺ 77 cm ² / 3

➺ 25 . 66 cm ²

Hence, area of sector is 25. 66 cm ².
