Compare to the general equation of a circle centered at (h,k) with radius, R.
\n" ); document.write( "\"%28x-h%29%5E2%2B%28y-k%29%5E2=R%5E2\"
\n" ); document.write( "a) \"R%5E2=49\", points on the circle include (R,0), (0,R),(-R,0),(0,-R)
\n" ); document.write( "b) \"R%5E2=1.44\", points on the circle include (R,0), (0,R),(-R,0),(0,-R)
\n" ); document.write( "
