A cone with included interior is 3-dimensional. However, if you are not including the interior it is a 2-dimensional surface residing in a 3-d ambient space.
If you're utilizing the common topological definition of dimension, you can derive that a cone (surface only) is 2 dimensional by looking at its open sets.
A circle is a two-dimensional figure, where the cylinder and cone are three-dimensional.

yes
Three dimensional objects, such as a cone, do not have a perimeter in any meaningful way.

A cone perhaps
A cone with a cylinder at the apex.
pyramid or cone
Because the base of a cone is round, it is the only three dimensional figure with only one vertex.
