Expert Answer:

symmetrical bodies having homogenous distribution of mass over the volume:
 
we take a elemental volume at a particular distance
then we integrate it over the whole object to calculate the mass
center of mass is defined as:
R = ?(M.r)/?r
thus here it will be R = ?M.r dr/?dr               (here M is a function of r)
