calculate moments of inertia

Hi everyone,I got a question here and I thought I have solved it,and I've double checked my answer again and again,but I still get different answer compare to solution.I really feel solution is wrong,can anyone help me please?

Consider the solid region that is bounded by the top half of the hyperboloid of two sheets and the plane .

If the mass per unit volume is ,find the three moments of inertia , ,and .

I got same answer for ,so please don't worry for it.My problem is just and ,and for sure they are equal.

I used spherical coordinate to calculate.Also the formula . I did times by Jacobian as well.

My final answer is ,but solution is .

Can anyone please help me? Thanks a lot.
