What is the length of the arc of a circle whose radius is 35 cm and whose arc subtends an angle of 72° at the centre of the circle?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 44 cm
The radius of the circle (r) = 35 cm
The angle subtended by the arc at the center of the circle (θ) = 72°
Length of the arc of the circle = (θ/360) × 2πr = (72/360) × 2 × (22/7) × 35 = 44 cm
