Simplifying temperature profile

I am given the temperature profile below and the two equations:



> 
> $$Q = (2\pi R\_0)LU\_0(T\_{1\infty}-T\_{2\infty})\tag1\label1$$
> $$\frac{1}{U\_0R\_0} = \frac{1}{h\_1R\_0} +\frac{\ln(R\_\mathrm a/R\_0)}{k}+ \frac{1}{h\_2R\_\mathrm a}\tag2\label2$$ 
> 
> 
> [![temperature profile](https://i.stack.imgur.com/sPXzG.png)](https://i.stack.imgur.com/sPXzG.png)
>

and I am asked

I am not sure if this means that I am supposed to "remove" the middle term in \eqref{2} since it will more or less be the same as the first term and thus the overall heat transfer coefficient would look like this:


$${U\_0} = \left(\frac{1}{h\_1} + \frac{R\_0}{h\_2R\_\mathrm a}\right)^{-1}$$ 


What I don't understand is that I just simplified $\ce{Eq(2)}$ and not \eqref{1} which the question asks for. Or is it that by simplifying \eqref{2} I in turn simplify \eqref{1}, or have I completely misunderstood the question.
