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.

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

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.

3. Perform a similar procedure for the lower base.

4. Glue the base.

We suggest you build 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.
