Question
A sector of a circle has a central angle of 120°. The
radius of the circle is 14 cm. Find the area of the sector.Solution
The area of a sector is given by the formula: Area = (θ / 360) × πr², where θ is the central angle in degrees and r is the radius. Area = (120 / 360) × π × 14² Area = (1/3) × 22/7 × 196 Area = 205.33 cm². Answer: d) 205.33 cm²
