What is the area of the sector in a circle of radius 18 cm, if the angle subtended at the center is 120°?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 108π.

Area of sector = θ360×πr2\frac{\theta}{360} \times \pi r^2

⇒ (120/360) × π × 18 × 18

⇒ 6 × 18 × π =108π
