The standard equation for a circle is:
\n" ); document.write( "(x - h)^2 + (y - k)^2 = r2
\n" ); document.write( "where h and k are the x- and y-coordinates of the center of the circle and r is the radius.
\n" ); document.write( ".
\n" ); document.write( "Now, let's look at your problem.
\n" ); document.write( "x^2 + (y - 1)^2 = 36
\n" ); document.write( "we can rewrite it as:
\n" ); document.write( "(x-0)^2 + (y - 1)^2 = 6^2
\n" ); document.write( ".
\n" ); document.write( "Based on the above, we now have:
\n" ); document.write( "h=0
\n" ); document.write( "k=1
\n" ); document.write( "r=6
\n" ); document.write( ".
\n" ); document.write( "center = (h,k) = (0,1)
\n" ); document.write( "radius = r = 6 \n" ); document.write( "

\n" );
