Solve for h
Solve T = 2pR(R + h) for h

$T=2\pi R\left(R+h\right)$

First, divide both sides of the equation by $2\pi R$ to get:

$\frac{T}{2\pi R}=R+h$.

I'll leave it to you to finish the rest of this problem.

Is the answer (T/2piR) - R = h?

Yes. However, you can rewrite the answer as $\frac{T-2\pi R^2}{2\pi R}$ if you combine the two terms.
