Algebra.Com's Answer #471782 by 303795(602) ![]() You can put this solution on YOUR website! If the wheel makes 4000 revolutions in travelling 44000 metres (44 kilometres) then one revolution must be 44000/4000 = 11 metres so the circumference of the wheel will have to be 11 metres as well. \n" ); document.write( "Using the formula for circumference of C = 2 x Pi x r \n" ); document.write( "11 = 2 x Pi x r \n" ); document.write( "so r = 11/(2 x Pi) \n" ); document.write( "=1.75 metres \n" ); document.write( " |
