how many edges , vertices and faces does a cylinder have? some say 0 edges,0 vertices, and 2 faces but others say 3 faces, 2 edges and 0 vertices. Which is it?
thank you.

a cylinder has 2 faces and no edges.
Oh? Check the site linked above.

I don't get it sadly
Well, it seems like the cylinder is being quite the shape-shifter, isn't it? Let's clear up the confusion and bring some order to its circus act!
A cylinder actually has two flat faces, one at the top and one at the bottom, which are circles. So, we've got 2 faces right there. In addition to those, a cylinder also has one curved face that wraps around its sides. That gives us a grand total of 3 faces.
Now, if you look closely, you'll notice that the curved face of a cylinder has two edges. Think of it as the cylinder's impressive mustache. So, there you have it, 2 edges.
Vertices, on the other hand, are those fancy corner points, and a cylinder doesn't have any sharp corners to show off. So, unfortunately, a cylinder doesn't have any vertices to invite to its geometrical tea party.
To sum it up, a cylinder consists of 3 faces, 2 edges, and 0 vertices. I hope that puts a smile on your face!
A cylinder is a three-dimensional shape that consists of two parallel circular bases connected by a curved surface. To determine the number of edges, vertices, and faces of a cylinder, let's break it down:
1. Edges: An edge is a line segment where two faces meet. For a cylinder, it has two circular bases and one curved surface. The circular bases have the same number of edges as the number of sides in their respective shapes (a circle has zero edges since it is a curved shape). Since the top and bottom bases have no edges, we need to consider the curved surface. The curved surface of a cylinder is like a rectangle that wraps around the circular bases, and it has two parallel edges. So, a cylinder has a total of two edges.
2. Vertices: A vertex is a corner or a point where edges meet. In the case of a cylinder, it does not have any vertices since there are no corners or points where the edges intersect.
3. Faces: A face is a two-dimensional surface that bounds a three-dimensional object. A cylinder has two faces: the circular top base and the circular bottom base. These two faces together enclose the curved surface of the cylinder. So, the correct answer is that a cylinder has three faces: two circular bases and one curved surface.
To summarize, a cylinder has 2 edges, 0 vertices, and 3 faces.
