\n" ); document.write( "find the center and radius of the circle\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2By%5E2=16\" \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2By%5E2=4%5E2\" if you compare it to \"%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2\", you see that \"h=0\" and \"k=0\" which means the center is at (\"0\",\"0\")\r
\n" ); document.write( "\n" ); document.write( "and \"r=4\"\r
\n" ); document.write( "
