the equation of the circle is
\n" ); document.write( " $\"%28x-x0%29%5E2%2B%28y-y0%29%5E2=R%5E2\"$
\n" ); document.write( "Where (x0, y0) is the center, R is the radius of the circle
\n" ); document.write( " $\"4x%5E2+%2B+4y%5E2+-+9+=0\"$
\n" ); document.write( " $\"4x%5E2+%2B+4y%5E2+=9\"$ divide by 4
\n" ); document.write( " $\"x%5E2+%2B+y%5E2+=9%2F4\"$
\n" ); document.write( "Hence, (0,0) is the center, R=3/2 is the radius \n" ); document.write( "

\n" );
