Algebra.Com's Answer #88225 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! The circumference of the wheel is found using the formula: \n" ); document.write( ". \n" ); document.write( "C = pi*D \n" ); document.write( ". \n" ); document.write( "where C is the circumference and D is the diameter. So for this problem: \n" ); document.write( ". \n" ); document.write( "C = pi*1.5 = 3.14*1.5 = 4.71 feet \n" ); document.write( ". \n" ); document.write( "Each turn of the wheel moves the car forward a distance equal to the circumference of the wheel \n" ); document.write( ". \n" ); document.write( "To move the car forward 37.68 feet the number of rotations (revolutions) the wheel must make \n" ); document.write( "is found by dividing 4.71 into 37.68 .... \n" ); document.write( ". \n" ); document.write( "Rotations = 37.68/4.71 = 8 \n" ); document.write( ". \n" ); document.write( "So, if the wheel rotates 8 times, the car will move forward 37.68 feet. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem. \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
