You can put this solution on YOUR website! a pulley with a diameter of 13 inches is driven by a belt which is moving 1252 ft/min. To the nearest unit, how many revolutions per minute are made by the pulley.
------
circumference of the pulley = 13pi inches = (13/12)pi ft
------------------------
# of revs/min = 1252 ft/min ; (13/12)pi ft = 367.87 rev/min
