A circular jogging track has a radius of 50 m. A runner covers a curved path that subtends an angle of 120° at the center. What is the length of the arc she runs?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. m
Arc length = (θ / 360) × 2 × π × r
Arc length = (120 / 360) × 2 × π × 50
Arc length = (1/3) × 2 × π × 50
Arc length = 100π / 3
