\n" ); document.write( "the standard equation of a circle is:\r
\n" ); document.write( "\n" ); document.write( " $\"%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2\"$ where $\"h\"$ and $\"k\"$ are $\"x\"$ and $\"y\"$ coordinates of the center, and $\"r\"$ is radius\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "given:
\n" ); document.write( " the center is at ( $\"-2\"$ , $\"-5\"$ ), so we have $\"h=-2\"$ and $\"k=-5\"$ \r
\n" ); document.write( "\n" ); document.write( "and $\"r=+sqrt%282%29+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x-%28-2%29%29%5E2%2B%28y-5%29%5E2=%28sqrt%282%29%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x%2B2%29%5E2%2B%28y%2B5%29%5E2=2\"$ -> your equation \n" ); document.write( "

\n" );
