A cylinder is a geometric solid bounded by a cylindrical surface and two parallel planes intersecting it.
A cylinder refers to a group of solids formed by rotating a flat geometric figure around an axis.
How can you make a cylinder of paper?
You can build a cylinder model with the following characteristics: height 150 mm, base diameter 65 mm.

A truncated cylinder is a geometric body that is cut off from the cylinder by a plane that is not parallel to the base.
Here you can build a model of a truncated cylinder with the following characteristics: height 165 mm, base diameter 65 mm, 45° angle of inclination for the section plane.

Assembly scheme of a truncated cylinder:
1. Connect the pattern so that you get a tube.
2. To avoid difficulties and shifting when gluing the bases, we recommend that you first glue the auxiliary elements. This will allow you to hold them smoothly when gluing and will create the correct shape of the geometric structure.
3. Perform a similar procedure for the lower base.
An example of a truncated cylinder from architecture:
In 1989, a planetarium in the shape of a truncated cylinder was built in Copenhagen (Denmark).
