document.write( "As you can see the green line segment is the diameter of the circle and it\r\n" );
document.write( "is the same length as the edge of the square, so the diameter of the circle\r\n" );
document.write( "is also 8 cm.  Since the radius of the circle is one-half of the diameter\r\n" );
document.write( "the radius of the circle is 4cm.\r\n" );
document.write( "\r\n" );
document.write( "Area of square = side² = (8cm)² = 64 cm²\r\n" );
document.write( "\r\n" );
document.write( "Area of circle = pr² = (3.14)(4cm)² = (3.14)(16cm²) = 50.24 cm²\r\n" );
document.write( "\r\n" );
document.write( "Area of waste =  Area of square - Area of circle = (64 cm²)-(50.24 cm²) = 13.76 cm²\r\n" );
