Summary

• This lesson is designed to understand and compare the volumes of cylinders and cones.

Learning objectives

• The cylinder and the cone
• Calculating the high, radius and volume of the cylinder and cone

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 cone and cylinder
• explanation with the sketch
• concrete task

1. You have a cone. The height is 12 cm, the radius is 5 cm. Calculate the volume of the cone. What is the volume of the cylinder with the same radius and height? Compare your results and write down the conclusion. Print the cone and cylinder.

2. You have a cylinder. The height is 7 cm, the radius is 3 cm. Calculate the height of the cone with the same volume and the same radius. Compare the height of a cylinder and cone with the same base surface and the same volume. What can you see? Write it down. Print the cone and cylinder.
