Algebra.Com's Answer #27261 by fractalier(6550) You can put this solution on YOUR website! The minute hand is a radius of a circle...the circumference C = 2(pi)r or \n" ); document.write( "C = 2(22/7)(1.12) (I imagine 22/7 is better than 3.14 this time) \n" ); document.write( "C = 7.04 m = 704 cm \n" ); document.write( "Now the minute hand goes around once each hour, or once every 60 minutes... \n" ); document.write( "Thus the tip covers 704 cm in 60 minutes or \n" ); document.write( "11.73 cm/min \n" ); document.write( " |
