Does a cone have an edge?

If a cylinder has two edges then a cone by that definition has one edge and one vertice.


A spatial figure with 2 circular bases no edge and no vertex?

One possibility is a cylinder whose bases do not stop in edges but flow gradually into the length of the cylinder.


Circumference of a cylinder?

It is the distance measured round its edge. multiply the radius (half the distance across it) by 3.14159


What shape has two edges and no vertices?

Any time we connect two edges we create a vertex. The only way a shape can have two edges and no vertices is if the edges are disconnected. For example, two parallel lines is two edges and no vertices. If you are thinking of polygons, we need at least 3 edges and they must be connected. So the answer to your question is really there is not shape that fits this description if we restrict ourselves to planar closed figures. The above is true for polyhedra. However, a cylinder meets the requirements if we consider the case where an edge is defined in such a way that a cylinder has two of them. The word "if" is there because sometimes, an edge is required to be straight. In that case a cylinder has none. However, many texts are not precise about how they define and edge and in this case we have no definition at all. So it is important to point out that the answer is a cylinder or nothing depending on your edge definition. If we use the definition of an edge as boundary between smooth surfaces making up an object, then a cylinder has two edges. There are similar issues with the term vertex and how it is used in general language, in toplogy and in graph theory. For this question, I think a good answer is a cylinder is the edges and vertex are appropriately defined. The link will help with more details for those interested.


How many possible outcomes are there if you toss a fair coin four times?

Normally there would considered to be 2⁴ = 16 possible outcomes as each outcome is one of 2 states: Head or Tails. ------------------------- There is an extremely small probability that a normal coin will end up on its edge, which mean there are 3⁴ = 81 possible outcomes. However, this probability is so small that it is ignored and normally only 2 outcomes are considered possible. As the radius to width ratio of the coin changes, the probability of the coin ending up on its edge changes, for some values being so significant that it becomes a real probability that the edge can result, and for some ratios it is almost always the edge that results and the probability of head or tails (ie ends of the cylinder that is the coin) is so small as to be ignored like the edge for a normal sized coin (cylinder).
