Find the length of the arc on a circle of radius r intercepted by a central angle (pheta).Round answer to one decimal place. 
r=13.6in, (pheta)=150 degrees
---
Circumference of the circle = 2pi*r = 2*pi*13.6 = 27.2pi in.
----


arc = (150/360) = 5/12 of the circumference
---
arc length = (5/12)(27.2pi) = 35.60.. inches
