Mathematically, a cone is infinite and so has no flat surface. The popular cone is actually a truncated cone and does have 1 flat surface.
Its base is a flat surface
a cone has one flat surface one vertex and no edge.
A cone !!
its a cone cones dont have a flat bottem
A cone has 1 flat surface, because a cone has 1 corner and has 4 edges. The reason that is is because a cone is round. A cone has a flat surface at the bottom of the cone. The reason it is because the cone doesn't have any vertices and most of the solid and plane figures have vertices.
Just one at the base, the rest is a curved surface
you are a cone
