A pulley with a radius of 8 inches rotates three times every five seconds. Find the angular velocity of the pulley in radians/sec (round to the nearest hundredth). Find the linear velocity to the nearst ft/hr.
***
let C=circumference of 8 inch pulley
C=pi%2Adiameter=16%28pi%29+inches

cross out: rev, sec, inches
linear++velocity=3%2A16%28pi%29%2A3600%2F%285%2A12%29=9047.79+%28ft%2Fhr%29
