This is a good one.
According to the definition in geometry a vertex is a corner.
A triangle has 3 vertices
A square has 4 vertices
So far it is a piece of cake.
So how many corners does a sphere have?
If we have to approximate a sphere (actually I’m thinking of a circle but for our argument it is good enough) we would need infinitely many edges (or sides) and therefore would generate infinite number of vertices since a vertex is formed between every two edges.
So a sphere has infinite number of vertices.
Some people would say that it has a zero vertices since there are no corners to a sphere. But now you know better don’t you?

A vertex (pl. vertices) is basically the name for a 'corner' on a 3D shape, and a corner is where edges meet. A sphere only has one face, so it has no edges, so it has no vertices.
Yes you could argue that the answer is infinite, but if this is school mathematics we're talking here, then the answer your teacher wants to hear is zero.

a sphere has vertices?
I have no clue.
I thought I was confused, but its not me its you.
in geometry, a vertex (Latin: corner; plural vertices) is a corner of a polygon (where two sides meet) or of a polyhedron (where three or more faces and edges meet).
The answer would either be none or infinite. That seems like a philisophical question by this definition.

A circle is a perfectly curved line and only exists in the mind. Similarly, a sphere is sort of a 3-D Circle, The Great circle, or the circle that intersects the center of a given sphere, is omnipresent in the circle. Confusing, eh?
Bottom line:
A Sphere has 0 vertices.

How can a sphere have verticles it is a solid circle why dont you study geometry I hope this helps you rweally need to study I would be sorry to be your teacher.

a sphere is round - no vertices

none, its a 3 demensional circle
if you need the equations for finding volume or surface area of sphere, contact me

infinite or zero. t's radius is equidistant from the center in every possible direction, therefore it cannot have a vertice. It is a trick question.

vertices arew faces right, so it should be 3, or none, hell i dunno!
