Yes.
The 3D shape with one face and one vertex is a cone. A cone has a circular base that serves as its singular face, while the point at the top where all the lines from the base converge is the vertex. It can also be considered an apex, where the shape tapers to a single point.
The bottom or (Base) of a shape. Example...
Yes. A base on a polyhedron is a face and a base on a polygon is a side.
Any face that is not a base is a what
It depends on the shape of the base. A pyramid or a prism can have any polygonal shape as base and the formula for its area will depend on the shape. With other solid figures, the base may simply be the face tat the object happens to be "sitting" on: roll it and another face becomes the base.
The handsome part is the shape of the face
sphere
It is the base/face of a certain shape, as in a square, it would be the bottom line(the one on/closest to the ground).
A solid shape with one face is known as a "hemisphere." A hemisphere is half of a sphere, which means it has a curved surface (the face) and a flat circular base. While it doesn't have multiple distinct faces like other solids, it can be considered as having one continuous surface.
Cone
sphere
The shape of the face on a cone is a circular base at the bottom and a curved surface that narrows smoothly to a point called the apex. This curved surface is referred to as the lateral face of the cone. Overall, a cone has one circular face (the base) and one curved surface.
