\n" ); document.write( " \"x%5E2%2B+y%5E2=49+\"\r
\n" ); document.write( "\n" ); document.write( " \"x%5E2%2B+y%5E2=7%5E2+\"-> here you have a circle\r
\n" ); document.write( "\n" ); document.write( "compare to a standard formula \"%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2\" you can see that\r
\n" ); document.write( "\n" ); document.write( "\"r=7\"
\n" ); document.write( "\"h=0\"
\n" ); document.write( "\"k=0\"\r
\n" ); document.write( "\n" ); document.write( "so, you have a circle with center at origin and a radius equal to \"7\"\r
