A ball is a three -dimensional body limited by the sphere. The sphere is a surface consisting of all points equivalent from the center of the ball.

The main properties of the ball

All points of the ball are at the same distance from the center. The radius of the ball is the distance from the center to anywhere on the surface of the ball. The diameter of the ball is a segment connecting two points on the surface of the ball and passing through the center of the ball. The volume of the ball is a value equal to 4/3πr^3, where R is the radius of the ball.

Ball Types of balls

The balls can be divided into two main types:

A smooth ball is a ball, the surface of which does not have protrusions or recesses. A rough ball is a ball, the surface of which has protrusions or recesses. Applications of balls

Balls are used in many areas, including:

In physics, to describe the shape of atoms and molecules. In astronomy, to describe the form of planets and other cosmic objects. In engineering, for the manufacture of various parts and structures. In sports, for the manufacture of balls and other sports shells. In art, to create various sculptures and installations. Balls are simple and universal figures that are used in many areas of life.
