Algebra.Com's Answer #534635 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 3 inches, and the larger gear has a radius of 7 inches. \n" ); document.write( " two circles touching at one point. Larger circle has radius of 7 inches. Smaller circle has radius of 3 inches. \n" ); document.write( "===== \n" ); document.write( "Larger circumference: 2pi*r = 14pi inches \n" ); document.write( "Smaller circumference: 2pi*r = 6pi inches \n" ); document.write( "-----\r \n" ); document.write( "\n" ); document.write( " Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation? \n" ); document.write( "Ans: (6pi/14pi)(360) = (3/7)360 = 0.4286(360) = 154.29 degrees \n" ); document.write( "----------------------------------------------------- \n" ); document.write( " Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear? \n" ); document.write( "Ans: # of rotations = 14pi/6pi = 7/3 = 2 1/3 rotations \n" ); document.write( "====================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "---------------------------- \n" ); document.write( " |
