How many flat and curved surfaces on a sphere?

How many flat and curved surfaces on a sphere?

A sphere has one face and this face is curved. Thus, a sphere has a curved faces. A cylinder has three faces.

Does a sphere have a flat or curved surface?

a sphere has a single curved surface and no edges or vertices. an apex. To make it clearer, the face can be called a base and the point is the apex, not a vertex.

Can spheres be flat?

A topological sphere can have a geometry that is flat except at a finite number of points: for example, the regular polyhedra are spheres that are flat except at their vertices. At the vertices themselves, the curvature becomes infinite, in such a way that its integral gives the deficit angle at that vertex.

How many surface are there in sphere?

A sphere is a three-dimensional round-shaped object. Unlike other three-dimensional shapes, a sphere does not have any vertices or edges. All the points on the surface of the sphere are equidistant from its center….Sphere.

What is a flat surface?

A surface that is not curved.

How many surface does sphere have?

How many surfaces does a hollow sphere have?

one surface
The total surface area of a hollow sphere is equal to the CSA of hollow sphere as a hollow sphere has only one surface that constitutes it.

How many surfaces does a sphere have?

What is a flattened sphere?

A spheroid, or ellipsoid, is a sphere flattened at the poles. The shape of an ellipse is defined by two radii.

What objects have the shape of a sphere?

Examples of Sphere

  • Ball.
  • Planets.
  • Moon.
  • Sun.
  • Eyeball.
  • Orange.
  • Marbles.

Does a sphere have a curved surface?

A sphere has no edges and therefore no corners. It has one curved face that goes all the way around.

How many dimensions does a flat surface have?

surface, In geometry, a two-dimensional collection of points (flat surface), a three-dimensional collection of points whose cross section is a curve (curved surface), or the boundary of any three-dimensional solid. In general, a surface is a continuous boundary dividing a three-dimensional space into two regions.

How many 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 does a sphere have?

A sphere is ball-shaped and is perfectly round, which means that it is not longer in a particular direction than any other. A sphere has: 1 face, 0 edges and 0 vertices. It can help to pick up a spherical object and feel for edges and vertices when teaching these.

What are the attributes of a sphere?

A sphere is a perfectly round three dimensional shape similar to a round ball you might play soccer or basketball with. All points on the surface of a sphere are the same distance from the center. A sphere is perfectly symmetrical around its center. The distance from the center of a sphere to its surface is called the radius.

Does a sphere have a face?

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.
