## Summary

The lesson about the cylinder

## Learning objectives

• An equilateral cylinder
• An axial cross-section
• Calculating the high, radius, surface and volume of the cylinder

## Teacher preparation

• Discussion of tools and 3D printing. Calculation task.
• A reconsideration of how basic operations are conducted.
• Discuss how to upload a file (STL) to a print program – individually when appropriate.

## Teacher explanation

• repeating the properties of the cylinder
• explanation with the sketch
• concrete task
1. You have an equilateral cylinder. The height is 6 cm. Calculate the surface of an axial cross-section, the surface and volume of the cylinder. Print the cylinder.
2. You have an The height is 6 cm. The volume is 150π cm3. Calculate the radius, surface of an axial cross-section and the surface of the cylinder. Print the cylinder.
