A sector of a circle with radius 14 cm has a central angle of 135°. Find the area of the sector.
Show answer & explanation
Correct answer: D
Explanation
Given:
Radius r = 14 cm
Angle = 135°
According to the formula:
Area = (θ/360) × πr²
= (135/360) × 22/7 × 14²
= (3/8) × 22/7 × 196
= (3/8) × 22 × 28
= (3/8) × 616
= 231 cm²
