1. Review old knowledge

We have learned to calculate the volume of a cylinder. Could you please recall how to calculate the volume of a cylinder?

2. Explore new knowledge

Is there any relationship between the volume of the cone and the volume of the cylinder?

Can you guess the relationship between the volumes of cylinders and cones of equal base and height?

How to calculate the volume of a cone?

3. Application of knowledge

(1) Do it

1. A conical part has a base area of ​​19cm2 and a height of 12cm. What is the volume of this part?

2. A conical plumb bob made of steel, with a base diameter of 4cm and a height of 5cm. Steel weighs approximately 7.8g per cubic centimeter. How many grams does this plumb bob weigh? (Keep the result as an integer)

(2) Solve problems

1. Fill in the blanks

(1) The volume of a cylinder is 75.36m³, and the volume of a cone with the same base and height as it is ( ) m³.

(2) The volume of a cone is 141.3m³, and the volume of a cylinder with the same base and height as it is ( ) m³.

2. The base area and volume of a cylinder and a cone are equal respectively. It is known that the height of the cylinder is 4dm, what is the height of the cone?

Think about it, when the base area and volume of a cylinder and a cone are equal respectively, what is the relationship between the height of the cone and the height of the cylinder?

3. A conical sand pile has a base area of ​​28.26m2 and a height of 2.5m. If this pile of sand is used to pave a 2cm thick pavement on a 10m wide road, how many meters can it be paved?
