A cam is in the shape of a circular sector. What is the perimeter of the cam if it has a radius of 1.875 cm and the central angle is 165.58 degrees?
**
arc length=radius*central angle in radians=half of the perimeter
165.58º=165.58*π/180=.9199π radians
=1.875*.9199π=1.7248π
Perimeter of cam=2*1.7248π=3.4496π cm
