consider a small element of mass dm and it’s distance from main axis then integrate for the entire body.
the moment of inertia of any body is given by dI = 
mdr2
Using this method you get for a solid cylinder 1/2MR2
And for a hollow cylinder approx. MR2
Please approve the answer if you like it and feel free to ask any follow up question :)
