[SOLVED] ratio H/R to in tensor problem, just making sure i did this right

1. The problem statement, all variables and given/known data
What is the ratio of height to radius that you need such that all the diagonal elements of the inertia tensor along its diagonal are equal?

2. Relevant equations

3. The attempt at a solution

Since my Ixx=Iyy i made one of them = to Izz, i did some simple algebra and got h/R = sqrt(3) is this right??? If not where did I go wrong?

Thanks
