- Given: Radius of the circle (r) = 6 cm, Angle of the sector (θ) = 60°.
- The formula for the area of a sector is (θ/360°) × πr².
- Substitute the given values into the formula: Area = (60°/360°) × (22/7) × (6 cm)².
- Simplify the expression: Area = (1/6) × (22/7) × 36 cm².
- Further simplification: Area = (22/7) × 6 cm².
- Calculate the final area: Area = 132/7 cm².
