Question

Find the area of the shaded sector of the circle

Answer 1

(175/9)π m²

Explanation:

Area of the shaded sector = θ/360 × πr²

Where,

θ = 180° - 110° = 70°

r = ½(20) = 10 m

Substitute

Area = 70/360 × π × 10²

Area = 7/36 × π × 100

Area = (7×100)/36π

Area = (700/36)π = (350/18)π = (175/9)π m²
