A cone has 1 face and 1 curved surface.
A cone has one face, but no edges or vertices. Its face is in the shape of a circle.
Congratulations, you are now the proud owner of what mathematicians call a Möbius strip (pronounced moe-be-us) – first discovered by the German mathematician August Ferdinand Möbius in 1858. It might just look like a twisted loop, but this strange shape really does have only one side.
Answer and Explanation: As a two dimensional object, yes a circle has a face, the area inside the circle.
Volume of a Sphere
So a sphere can be thought of as a polyhedron with an infinite number faces.
A sphere has no faces, a cone has one circular face, and a cylinder has two circular faces.
A cylinder is a three-dimensional shape. A cylinder has 3 faces.
The diamond shaped face is the rarest of face shapes, and is defined by a narrow forehead, wide cheekbones and a narrow chin. Diamond shaped faces are usually narrower at the eye line and jaw line, with high and often dramatic cheekbones.
A circle is a round shape that has no sides or corners.
A circle has 0 sides and 0 vertices (corners).
The digon can have one of two visual representations if placed in Euclidean space. One representation is degenerate, and visually appears as a double-covering of a line segment.
Properties of 3D shapes
A cone has 1 face, 1 curved surface, 1 edge and 1 vertex.
Cone has one circular face, one curved surface and one vertex.
Faces. A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one.
A heptahedron is a polyhedron with seven faces. There is a single "regular" heptahedron, consisting of a one-sided surface made from four triangles and three quadrilaterals. It is topologically equivalent to the Roman surface (Wells 1991).
A pentahedron is polyhedron having five faces.
An pentadecagon is a 15 sided polygon with interior angles that add to 2340 degrees.
In geometry, a heptadecagon, septadecagon or 17-gon is a seventeen-sided polygon.
How many faces, edges and vertices does a cone have? A cone has 1 vertex. A cone has 1 edge. A cone has 1 face and 1 curved surface.
A sphere has 1 curved surface, 0 flat faces, 0 edges and 0 vertices. A sphere is a 3D circle.
of course 1 face because a face is like a side and in 2d objects there is always only 1 face or it is on plane thats why it have only one face..
