If the radius of the circle is 42 cm, the angle formed at the center by an arc is 150°. What is the length of the corresponding arc?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 110 cm.
Arc Length = (θ/360) × 2πr
= (150/360) × 2 × (22/7) × 42
= 110 cm
Hence, the length of the corresponding arc is 110 cm.
