Given the equation of the circle is \"x%5E2-4x%2By%5E2-6y=3\".
\n" ); document.write( "x^2-4x + 4 + y^2-6y+9 = 3 +4+9
\n" ); document.write( "--------
\n" ); document.write( "(x-2)^ + (y-3)^2 = 16
\n" ); document.write( "----------\r

\n" ); document.write( "===========
\n" ); document.write( "Hence find out the
\n" ); document.write( "centre:: (2,3)
\n" ); document.write( "-------
\n" ); document.write( "area = pi*4^2 = 16pi square units
\n" ); document.write( "-------
\n" ); document.write( "circumference of the circle = 2*pi*4 = 8pi units
