Hydrogen Atom: Line Spectra and the Bohr Model

A singly ionized helium atom (He+) has only one electron in orbit about the nucleus. What is the radius of the ion when it is in the n = 3 excited state?

I have an idea of how to do the problem, but that is with hydrogen. Please help and thank you very much!
