You mean, "distance between their centers is 14 cm."

R radius for big circle
r radius for small circle

AND .

A good guess is that you are using as an approximation for . This would allow simplifying your system of equations into:
-

AND

-

The system should be solvable without much trouble; say if you find too much difficulty in continuing and finishing.
