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
two
a cone has one flat surface one vertex and no edge.
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.
its a cone cones dont have a flat bottem
Just one at the base, the rest is a curved surface
no
A cone !!
a cone.
It only has one. the face going around the cone is called the lateral surface
None. A cone is a surface of revolution and thus it has no flat sides. Polygons are planar figures. A cone has no planar faces.
