4. Characteristics of circles and cones.

1. cone, a term in the field of mathematics, has two definitions. Analytic geometry definition: A spatial geometry consisting of a conical surface and a plane intersecting it (the intersection line is a circle) is called a cone.

2. Definition of solid geometry: The rotating body surrounded by a straight line with a right-angled side of a right-angled triangle is called a cone, and the right-angled side is called the axis of the cone. There are also sand piles, funnels, hats, gyroscopes, hats, pencils, drills, plumbs, etc. Everything in life can be approximately regarded as a cone.

3. Sweet cones are also indispensable in daily life. The following are the characteristics of a cone: the straight line on the right side of a right triangle is the axis of rotation, and the object surrounded by the rotation of the other two sides is called a cone.

4. A cone consists of a vertex, a side surface and a bottom surface, and the distance from the vertex to the center of the bottom surface is the height of the cone.

The cone has two faces, the bottom is round and the side is curved.

6. Let the cone expand along the generatrix, which is fan-shaped. The volume of a cylinder is equal to three times the volume of a cone with the same base and height, which is called a cone.
