# Cone net. How to make pdf template

A cone refers to a group of solids formed by rotating a flat geometric shape around an axis. In the case of a cone, rotation occurs relative to one of a right triangle leg.

# How can you make a cone of paper?

Here you can build a truncated cone model with the following characteristics: height 185 mm, base diameter 90 mm. Download cone net

What is the cross-section of the cone?
Depending on the angle of inclination of the section plane to the base of the cone, four sections can be formed: a circle, an ellipse, a parabola, a hyperbola.

An example of architecture: the base of the Ostankino television tower in Moscow has the shape of a truncated cone:

You can build a truncated cone model with the following characteristics: height 185 mm, base diameter 90 mm, 55° section plane inclination angle, ellipse-shaped section. Download net truncated cone with an ellipse section.

The elliptical cone assembly scheme:
1. Connect the parts so that you get a tube.
2. To avoid difficulties and shift when gluing the bases, we recommend that you first glue the auxiliary items. This will allow you to hold them smoothly when gluing and create the geometric structure correct shape.

3. Perform a similar procedure for the lower base.
4. Glue the base.

We suggest you building a truncated cone model with the following characteristics: height 110 mm, base diameter 100 mm, 65° section plane inclination angle, slice thickness relative to the base 10 mm, parabola section shape.
Download a net of a truncated cone with a cross-section of a parabola (or parabolic cone).
