you are a cone
The square based pyramid does not stack or roll.
The object described is a cone. A cone has one vertex (the point where the flat face meets the curved surface) and one flat face (the circular base). Due to its shape, a cone can roll along a flat surface smoothly.
A cone.
The interception of a plane with a cone parallel to the base of the cone is a circle.
Yes. A cone will roll following a circular path with the central axis being the point of intersection of the sides of the cone (which is the point of a pointed cone).
