Finding Radius of Nucleus Issues

Question: https://gyazo.com/60da67b94d9f4a1d5f7e1d971c1c46b4
I know i'm supposed to use the equation R = R(A)^(1/3) but I don't know how to answer the question

Let R_C be the radius of carbon-12 and R_U be the radius of uranium-238.
R_C / R_U = (A_C)^(1/3) / (A_U)^(1/3)

I am not sure what you have done. You can check on the link below to see the computation.
