document.write( "The area of the ring-shaped path is the difference of the areas\r\n" );
document.write( "of the larger and smaller circles. So we write\r\n" );

document.write( "\r\n" );
document.write( "    the area of the ring-shaped path =  -  =  = 675.1 yd^2.\r\n" );

document.write( "To determine the number of bags, we divide it by 7 yd^2\r\n" );
