Given:

Radius of circle = 5 cm

The angle subtended by a sector on the centre = 60°

Formula used:

Area of sector = (π × R2 × θ)/360°

Calculation:

Area of sector = (π × R2 × θ)/360°

⇒ (22/7) × (5)2 × 60°/360°

⇒ (22 × 25)/(7 × 6)

⇒ (11 × 25)/21 = 13.09 ≈ 13.1 cm2 

∴ The correct answer is 13.1 cm2.
