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
