Find the area of the sector of a circle with a radius of 5 cm and an angle of 60° (rounded off to one decimal).
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 13.1 cm2.
Area of sector = π × r2 × x/360
Given: r = 5 cm and x = 60°
Area of sector = 22/7 × 52 × 60°/360
⇒ 22/7 × 25 × 1/6 = 13.1 cm2
