Given a circle with a radius of 6, what is the length of an arc measuring 60°?

A.) 1/2pi

B.) 2pi

C.) 3/2pi

D.) 3pi

First, determine the circumference of the circle by the equation, C = 2πr.

C = 2π (6) = 12π

Then, multiply this value by the ratio of the angle and whole revolution,

12π x (60° / 360°) = 2π

Thus, the length of the arc is 2π.
