# How many curved edges does a sphere have?

An edge is where 2 faces meet, again some can be straight, some can be curved e.g. a cube has 12 straight edges whereas a cylinder has 2 curved edges. A corner is where 3 edges meet. A cube has 8 corners, as does a cuboid. A sphere has no edges and therefore no corners.

### How many faces are on a sphere?

All of these figures are curved in some way, so they have no edges or vertices. What about their faces? A sphere has no faces, a cone has one circular face, and a cylinder has two circular faces. Therefore, the number of faces increases by one from one figure to the next.
• #### How many faces are on a triangular pyramid?

It has 4 Faces. The 3 Side Faces are Triangles. The Base is also a Triangle. It has 4 Vertices (corner points)
• #### What is the definition of faces in math?

Face. In any geometric solid that is composed of flat surfaces, each flat surface is called a face. The line where two faces meet is called an edge. For example, the cube above has six faces, each of which is a square.
• #### What is a vertex in math?

From Latin: vertex "highest point" Definition: The common endpoint of two or more rays or line segments. Vertex typically means a corner or a point where lines meet. For example a square has four corners, each is called a vertex. The plural form of vertex is vertices.

### How many faces are in a cone?

A cone has one face. It is a three-dimensional shape with a circular base, one side and one vertex. Faces can be identified as the flat surfaces on a three-dimensional figure.
• #### How many sides does a cone have in 3d?

A cone has only one face - its base. Other people simply define a face as a 'surface' of a three-dimensional object. Using this definition, a cone would have two faces - its base and its curved face that ends in a point.
• #### How many edges are on a square pyramid?

The 4 Side Faces are Triangles. The Base is a Square. It has 5 Vertices (corner points) It has 8 Edges.
• #### What is a vertex in math?

From Latin: vertex "highest point" Definition: The common endpoint of two or more rays or line segments. Vertex typically means a corner or a point where lines meet. For example a square has four corners, each is called a vertex. The plural form of vertex is vertices.

• #### How many curved edges are there in a cylinder?

An edge is where 2 faces meet, again some can be straight, some can be curved e.g. a cube has 12 straight edges whereas a cylinder has 2 curved edges. A corner is where 3 edges meet. A cube has 8 corners, as does a cuboid. A sphere has no edges and therefore no corners.
• #### How many faces has a cylinder?

A cylinder has how many flat surfaces, vertices, and edges? Hi, A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners).
• #### Which solid has eight edges?

Rectangular Prism- it has 6 faces, 12 edges, and 8 vertices. Square Pyramid: it has a square base and triangular sides. There are 5 faces, 8 edges, and 5 vertices. Sphere: a curved, round solid figure.
