if question is too small then ill rewrite it:
A r and T are three variables. A is proportional to T^2 and A is also proportional to r^3.
T = 47 when r = 0.25
find r when T = 365 to 3s.f

We can do it more simply and without intermediate calculations in the following way. We have:
A ~ T^2
A ~ r^3
Thus, T^2 ~ r^3. So:
(T2/T1)^2 = (r2/r1)^3
So, now you can express r2 from here, then substitute the values.
