"Volume of a Cylinder" Cylinder and Cone PPT Courseware
Description
"Volume of a Cylinder" Cylinder and Cone PPT Courseware
1. Review old knowledge
Can we convert the cylinder into the three-dimensional figure we have learned and calculate its volume?
Could you please tell me how to calculate the volume of a cuboid or a cube?
2. Explore new knowledge
Cut the cylinder into pieces and put them together like this to get an approximate cuboid.
The more sectors it is divided into, the closer the three-dimensional figure is to a cuboid.
The volume of the cuboid is equal to the volume of the cylinder.
The base area of the cuboid is equal to the base area of the cylinder.
The height of the cuboid is equal to the height of the cylinder.
3. Application of knowledge
(1) Do it
1. A cylindrical piece of wood has a base area of 75cm2 and a length of 90cm. What is its volume?
75×90＝6750(cm3)
Answer: Its volume is 6750cm3.
2. Xiao Ming went out to play with his mother and brought a cylindrical thermos cup. When measured from the inside, the bottom diameter was 8cm and the height was 15cm. If two people need to drink 1L of water during a trip, is this glass of water enough?
(2) Solve problems
1. The volume of a cylinder is 80cm³ and the base area is 16cm2. How many centimeters is it high?
2. A cylindrical grain storage, the bottom radius measured from the inside is 1.5m, and the height is 2m. If each cubic meter of corn weighs about 750kg, how many tons of corn can this grain storage store hold?
Please think about it, if you want to know how many tons of corn this grain storage can hold, you need to know what this grain storage is?
4. Assign homework
Homework: Do it on page 26, question 2. Exercise 5 on page 28, questions 2 and 6.
