The problem statement,
I know how to find the cg of a solid by using cross section
but i just don't know how to find the cg of the cone by using the cg of a hollow cone
for eg, we can calculate the cg of the half sphere by 1. calculating the cg of the hollow half sphere, than use it to calculate the cg of solid sphere
the problem is that i can't write a equation for the dm of each hollow cone because x and y changes
i just want to know how to do it and in fact this is not a homework question
can anyone help me please?
