Algebra.Com's Answer #371107 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! one circular table has a diameter of 9ft and another circular table has a diamter of 20ft. how much greater is the larger table \n" ); document.write( "------------------- \n" ); document.write( "How much greater what? \n" ); document.write( "Circumference = pi*d \n" ); document.write( "C9 = 9pi \n" ); document.write( "C20 = 20pi \n" ); document.write( "------------ \n" ); document.write( " \n" ); document.write( "A9 = 81pi/4 = 20.25 sq ft \n" ); document.write( "A20 = 100pi sq ft \n" ); document.write( "-------- \n" ); document.write( "The area of the 20ft is (20/9)^2 times the area of the 9 ft. \n" ); document.write( "The difference in area = 100pi - 20.25pi = 79.75pi sq ft \n" ); document.write( " \n" ); document.write( " |
