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 edges does a triangle have?

    A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted .
  • How many edges faces and vertices are on a cone?

    Cone has 1 flat Face (the base) which is a circle. 1 curved Face ,1 Vertex , 1 Edge.. Cylinder has 2 flat Faces (top and bottom) both are circles .1 curved Face , 2 Edges ,No Vertices..
  • What is an edge in math?

    An edge is a line segment that joins two vertices (on the boundary or where faces meet). Example: This tetrahedron has 6 edges. Vertices, Edges and Faces.
B.

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.
  • What shape has a curved surface?

    These figures have curved surfaces, not flat faces. A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat. A cone has one circular base and a vertex that is not on the base.
  • Do 2d shapes have a face?

    They will talk about how many sides a 2D shape has, and whether the sides are straight or curved. It is very important that they handle 3D shapes in order to be able to count their faces, edges and vertices, so they will probably construct their own 3D shapes from nets.
  • How many edges does a sphere have?

    Logically I would say that a sphere has 1 face, 0 vertices and 0 edges. Problem: a face is flat, sphere is not flat. Secondly this does not satisfy Euler's formula v - e + f = 2. I would say a cone has 2 faces, 1 edge, and 1 vertex.
C.

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.
  • What is the face?

    The face is a central body region of sense and is also very central in the expression of emotion among humans and among numerous other species. The face is normally found on the anterior (frontal, rostral) surface of the head of animals or humans, although not all animals have faces.
  • What is a rectangular box called?

    A rectangular is a three dimensional shape with six rectangular shaped sides. All of its angles are right angles. It can also be called a cuboid. A cube and a square prism are both special types of a rectangular prism. Keep in mind, a square is just a special type of rectangle!
