Question 190113
<font face="Garamond" size="+2">

Arc Length is given by:

*[tex \LARGE \ \ \ \ \ \ \ \ \ \  2 \pi r \left(\frac{C}{360}\right)]

Where *[tex \LARGE r] is the radius of the circle, and *[tex \LARGE C] is the measure of the central angle in degrees.

Just substitute your values and do the arithmetic.  Since you weren't told to round to some precision, I would leave the answer in terms of *[tex \LARGE \pi]
