Calculation formula of sphere volume
The formula for calculating the volume of a sphere is: v = 4/3 π r 3.

Calculation formula of sphere volume: V = 4/3 π r 3. Analysis: three quarters times pi times the radius of the cube. A ball is a rotating body formed by taking a straight line with a semicircle diameter as the rotation axis and the semicircle surface rotates once, which is also called a sphere. The surface of a ball is a curved surface, called a sphere, and the center of the ball is called the center of the ball.

A space geometry, in which a semicircle rotates a Zhou Suocheng around a straight line equivalent to its diameter, is called a sphere, and the radius of the semicircle is the radius of the sphere. A sphere is a three-dimensional figure with only one continuous surface, which is called a sphere. The orthographic projection of a sphere on any plane is a circle with the same size, and the diameter of the projected circle is equal to the diameter of the sphere.

Definition of Sphere: A semicircle rotates a Zhou Suocheng around a straight line corresponding to its diameter. The space geometry is called a sphere. Sphere is a three-dimensional figure with a continuous surface, and the geometry surrounded by sphere is called sphere. There is no absolute sphere in the world. Absolute spheres exist only in theory.

Basic concept of spherical surface: a semicircle takes its diameter as the rotation axis, and the surface formed by rotation is called a spherical surface. The geometric figure surrounded by spheres is called sphere, which is called sphere for short. The center of the semicircle is called the center of the sphere. The line segment connecting the center of the sphere and any point on the sphere is called the radius of the sphere. The line segment connecting two points on the sphere and passing through the center of the sphere is called the diameter of the sphere.

The benefits of learning mathematics

People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.

For example, before solving a problem, I like to divide it into several sections, and each section is divided into several steps, so that I can dig slowly like a branch instead of thinking in confusion in front of a pile of data. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
