Algebra.Com's Answer #106016 by nerdybill(7384) You can put this solution on YOUR website! Area of a circle = pi(r^2)\r \n" ); document.write( "\n" ); document.write( "circular table w/diameter of 8ft has a radius of 4ft. \n" ); document.write( "circular table w/diameter of 10ft has a radius of 5ft.\r \n" ); document.write( "\n" ); document.write( "area of circular table w/diameter of 8ft = pi(4^2) \n" ); document.write( "area of circular table w/diameter of 10ft = pi(5^2)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Difference in area: \n" ); document.write( "pi(5^2) - pi(4^2) \n" ); document.write( "= pi(25) - pi(16) \n" ); document.write( "= pi(25-16) \n" ); document.write( "= pi(9) \n" ); document.write( "= 3.14(9) \n" ); document.write( "= 28.26 \n" ); document.write( " \n" ); document.write( " |
