A circle has a radius of 6 in. What is the exact length of an arc formed by a central angle measuring 45°? Enter your answer in the box. Express your answer using π . in.

Arc Length = radius * theta (in rads)

{ 45° = pi/ 4 rads }

Arc Length = 6 * (pi / 4) in = 6pi/4 in = 3/2 pi in = 1.5 pi inches

Awesome Cphill!
