An electric hoist is being used to lift a beam. The diameter of the drum on the hoist is 13 inches, and the beam must be raised 3 feet. Find the number of degrees through which the drum must rotate. Round your answer to nearest whole number.
-------------
r = d/2 = 6.5 inches
3 ft = 36 inches
Angle = 36/6.5 radians = 72/13 radians
degs = (72/13)*180/pi
=~ 317 degs
