general equation for a circle is ___ (x - h)^2 + (y - k)^2 = r^2
\n" ); document.write( "___ this is a circle, centered at (h,k), with radius r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in this case, the center is (0, -4) and the radius is 7
\n" ); document.write( "
