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.
\n" ); document.write( "------
\n" ); document.write( "circumference of the pulley = 13pi inches = (13/12)pi ft
\n" ); document.write( "------------------------
\n" ); document.write( "# of revs/min = 1252 ft/min ; (13/12)pi ft = 367.87 rev/min
\n" ); document.write( "---------------
