sphere has how many vertices?

A vertex is a corner where edges meet. The plural is vertices. For example a cube has eight vertices, a cone has one vertex and a sphere has none.

['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.', 'Edges. An edge is where two faces meet. ... ', 'Vertices. A vertex is a corner where edges meet.']

Vertices are points, edges are line segments that join the vertices and faces are the "flat" parts bounded by edges. So a rectangular box has 8 vertices, 10 edges and 6 faces.

Also, there is no need to consider the left and right faces and their opposite vertices, because the triangles will be duplicated. Thus, we can construct 56 distinct triangles by joining three different vertices of a cube.

In five dimensions, they are: The 5-simplex of the simplex family, {3,3,3,3}, with 6 vertices, 15 edges, 20 faces (each an equilateral triangle), 15 cells (each a regular tetrahedron), and 6 hypercells (each a 5-cell).

Cube. A cube has six equal, square-shaped sides. Cubes also have eight vertices (corners) and twelve edges, all the same length. The angles in a cube are all right angles.

A rectangular pyramid has 5 faces. Its base is a rectangle or a square and the other 4 faces are triangles. It has 8 edges and 5 vertices.

In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.

You can plug in 12 for F and 20 for V and then solve Euler's formula for E. Let's look. So, the number of edges is 30. This polyhedron has 12 faces, 20 vertices, and 30 edges.

A square pyramid has a square for a base and four triangles for sides. This means it has five vertices, or corners, and eight edges.

Hi Nicholas, The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 πr2 = 1062.
