there's the hour hand and the minute hand and the second hand.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the second hand makes one complete revolution every minute.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "it is therefore progressing through 2 * pi radians every minute because there are 2 * pi radians in a complete circle (2 * pi radians is equal to 360 degrees).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "one day is equal to 24 hours * 60 minutes per hour = 1440 minutes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "there are 7 days in a week, therefore 1 week is equal to 7 * 1440 = 10080 minutes.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "each minute has the second hand traveling through 2 * pi radians, therefore 10080 minutes has the second hand traveling through 10080 * 2 * pi = 20160 * pi radians.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that should be your answer.\r
