Area of circle is smaller than area of the square. The nonwatered area is the part of the square which is not in the circle. The nonwatered area is outside the circle but still in the square.\r

The amount of area outside the circle but inside the square which is nonwatered is $\"x%5E2-pi%2Ar%5E2\"$ . \n" ); document.write( "
