A plane
Wiki User
∙ 12y agoA group of points that extend forever in all directions is called a plane. We often draw a plane with edges, but it really has no edges.

The number of edges in a smokestack will depend on how you look at it. It probably has two edges to it, and here's why. A smokestack is basically a solid shape that is a hollow cylinder with a certain thickness. It has an inner and outer surface, and a surface on the top. We can ingnore the bottom surface or not, depending on what you are thinking of. Now let's focus. The top has two edges. There is the outer edge of the top of the cylinder, which divides the outer surface from the top surface. Then there is the inner edge of the top of the cylinder, which divides the inner surface from the top surface. So a smokestack has two edges. If you want to count the bottom (which you probably don't), add two more. Otherwise there are a pair of edges formed on the top surface of the cylinder, one around the outside and one around the inside.
Surface Area becomes 4 times the original when its edges are doubled because Suraface area = (edge)^2
The surface area is: 600 cm2

The landforms that extends into the ocean or sea is known as the continental shelf. The edges of the continental shelf are marked by a steep drop off into the ocean depths.
Liquids at the edges are in contact with the stationary pipe surface. The centre is furthest from the stationary pipe surface.
