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

R radius for big circle
r radius for small circle

highlight_green%28pi%2AR%5E2%2Bpi%2Ar%5E2=130%2822%2F7%29%29 AND highlight_green%28r%2BR=14%29.

A good guess is that you are using %2822%2F7%29 as an approximation for pi. This would allow simplifying your system of equations into:
-
highlight_green%28R%5E2%2Br%5E2=130%29
AND
highlight_green%28r%2BR=14%29
-

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