If a circle with radius=3, has a central angle of pi/6 radians, find the arc length associated with the central angle?

How do u do arc length?

My first thoughts would be: find angle, find circumference, ratio angle to 360 degrees times circumference.

Angle: Pi/6 radians = 180 degrees/6 = 30 degrees
Circumference: 2 x Pi x r = 6 Pi
Arc length: (30/360) x 6Pi = 1/2 Pi = 1.57
