"Surface Area of ​​a Cylinder" PPT courseware

Part One Content: Collaborative Exploration

There are countless heights of the cylinder, and the lengths of the heights are all equal.

Four-person group cooperation and exchange:

①What is the shape of the side of the cylinder when it is expanded along the height?

②The length and width of the expanded figure are related to which part of the cylinder? what is the relationship?

How to find the surface area of ​​a cylinder?

The length of the rectangle The width of the rectangle

Perimeter of the base of the cylinder Height of the cylinder

Side area of ​​cylinder = perimeter of base × height

S side area = 2πr×h

The surface of a cylinder consists of two bases, upper and lower, and one side.

Surface area of ​​cylinder = side area + area of ​​two bases
