What is the moment of the wheel.

Dimensions:
r= 1 m
h= 5 cm
m= 1000kg
a = 4120 rad/s2

I used the formula T = I * a

The moment of inertia can be calculate by Iz =(1/2)mr2or Ix=Iy= (m/12)* 3r2 +h2)

wich one do i need to use?

If you are trying to determine the torque, T, then the choice of moment of inertia, I, depends on the axis of rotation. Iz = mr2/2 is the one you would use if the wheel was in regular use, like on a car.
