# 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.A.

### 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**.

B.

### 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 faces has a cylinder?

#### 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.
