The area of the sector with central angle of 60° in a circular region whose radius is 5 cm is?
- 10.5 cm²
- 13.08 cm²
- 9.08 cm²
- None of these
Explanation
The area of the sector can be calculated using the formula: Area = (θ/360) * πr², where θ is the central angle and r is the radius.
Given θ = 60° and r = 5 cm, we can substitute these values into the formula:
Area = (60/360) * π * (5)²
Area = (1/6) * π * 25
Area ≈ (1/6) * 3.14 * 25
Area ≈ 13.08 cm²
