Because the sides are like a circle.
A cone can roll due to its circular base, allowing it to move smoothly across a flat surface. However, it does not stack well like other shapes, such as a cylinder or cube, because its pointed apex and sloped sides create an unstable structure when placed on top of another cone. As a result, while a cone can roll, it is not ideal for stacking.

cylinders: slide on the small sides, roll on the round one
sphere has 1 face and no vertex and it rolls but cone has 2 faces and it can roll and it has 1 vertex
