Let's focus upon the circle which i'll put at O :

y ^ 2 + x ^ 2 = 0.555 ^ 2
then if i interpret the drawing correct the other circle is at
(x + 0.4) ^ 2 + (y  0.195) ^ 2 = 1

If you are using the usual convention that up is positive y and right an positive x, the second circle's center is at (.40, .195). It's equation is
(x  0.4)^2 + (y  0.195)^2 = 1
