Description

"Understanding of Cones" Cylinder and Cone PPT Courseware 2

The sides of a cone are curved surfaces and the base is a circle.

The distance from the vertex of the cone to the center of the base is the height h of the cone.

Mark “√” if correct and “×” if incorrect

①The side surface of a cone is a curved surface. ( )

②The sides of a cylinder are rectangular when unfolded, and the sides of a cone are also rectangular when unfolded. ( )

③The line connecting the vertex of the cone to any point on the bottom is called the height of the cone. ( )

④The base of the cone is circular. ( )

Think about it: What is the difference between a cone and a cylinder?

There is only one and two identical circles on the bottom

High, there is only one, there are countless

Side curved surface, after unfolding, it becomes a fan-shaped curved surface, after unfolding along the height, it becomes a rectangle (square)

Make a cone out of cardboard, and then measure how many centimeters are its base diameter and height?
