Question: What is the length of the arc of a circle with a radius of 6 units that subtends an angle of 60 degrees at the center?

Options:

1. 2π units
2. 3π units
3. 4π units
4. 5π units

Correct Answer: 3π units

Solution:

The length of an arc is given by L = (θ/360) * 2πr. Here, L = (60/360) * 2π(6) = (1/6) * 12π = 2π units.
