Alright, thanks for clarifying :)

To be honest I don't think it is right. I've read some more based on what @.Scott said, and I think the correct strategy is to integrate the moments of the "slices" of the hemisphere (thickness dz) and then divide by the mass.

Place hemisphere in xyz coordinates so that the centre of the corresponding sphere is at the origin. Then notice that the centre of mass must be at some point on the z axis ( because the 4 sphere segments when cutting along the the xz and xy planes are of equal volume) y2 + x2 = r2 We want two...
