However, they all will change at percentage of the starting size

To wit: if expansion is X %, a three inch circle will expand to 3 in
+ *X% of three inches, while the little bit less than three inches
will expand to LBLT3in. + X% of LBLT3in, resulting in an ever widening
gap as temp increases.

In sum: the gap between inside and outside widens with increasing
temperature.

Thanks, Oz. And it doesn't matter if the object is a hollow cylinder
or solid rod; the dimension change is just a factor of the coefficient
of thermal expansion of the material?

Never mind...found the answer it's that the outside diameter delta is
the same whether or not its a solid or hollow object.
