Area of Hannah's circle is (pi)30^2
\n" ); document.write( "Area of Jonas's circle is (pi)20^2
\n" ); document.write( "So the difference is \"%28pi%2930%5E2+-+%28pi%2920%5E2\"
\n" ); document.write( "\"%28pi%29900+-+%28pi%29400\"
\n" ); document.write( "\"%28pi%29500\" is approximately 1570.796 cm^2
\n" ); document.write( "
\n" );
