\n" ); document.write( "\n" ); document.write( "There are 100 centimeters in a meter and 1000 meters in a kilometer, so there are 100,000 centimeters in a kilometer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The diameter of the tire is 75 cm, so the circumference of the tire is centimeters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence the number of revolutions of the tire when the car has gone 1 kilometer is .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the car is traveling at 110 km/hr, the number of revolutions in an hour is \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "But there are 60 times 60 or 3600 seconds in an hour, so the number of revolutions per second is:\r

\n" ); document.write( "\n" ); document.write( "Since there are radians in 1 revolution, the radian measure of the angle traversed by a point on the tire not located at the center of the tire would be:\r
