\n" ); document.write( "Write the standard equation of the circle with the given center\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-2%29%5E2+%2B+%28y-%28-6%29%29%5E2\" = \"r%5E2\",\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and find \"r\" as the distance between the given points\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r = \"sqrt%28%286-2%29%5E2+%2B+%28-1-%28-6%29%29%5E2%29\" = \"sqrt%284%5E2+%2B+5%5E2%29\" = \"sqrt%2841%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the final equation is \"%28x-2%29%5E2+%2B+%28y%2B6%29%5E2\" = 41.\r
\n" ); document.write( "
