Under what conditions will the ball be equal to the sphere?

How many minimum points can a ball consist of?
How many points can a sphere minimally consist of?
I am not sure what you are asking. Between two points in any space you can have an infinite number of sub divisions mathematically.
Physically you are restricted to the Planck length.
 
I don't understand what you're asking either.

1. What, in your view is the difference between a 'ball' and 'sphere'?

2. Points have zero dimensions. Any shape with one or more dimensions contains an infinite number of points.

Your question is not well-formed.
 
So, the number pi will never be calculated?
Certainly not by counting the points on a sphere, no!

Pi is a mathematical object, it cannot be measured in the real world to an arbitrary level of precision.

Currently, it has been calculated to 100 trillion digits.

Зачем его вообще считают? Какой в этом смысл?
 
You would enjoy Carl Sagan's novel 'Contact'. It finds a nice balance between your interest in science and your interest in god. And it does so using pi.

How many minimum points can a ball consist of? How many points can a sphere minimally consist of?

Instead of size-less points, one would need an arrangement of shapes, if seeking a minimum amount of units to tile around a globular solid. A common soccer ball, for instance, consists of a pattern of 20 hexagons and 12 pentagons. But those are not stiff material -- they bend, as a ball stitched together with even fewer geometric shapes would better illustrate via maintaining its sphericity. If replaced by stiff parts, even a polyhedron made out of 30 hexagons and 12 pentagons would be just that -- a polyhedron, rather than a sphere ("perfectly" rounded).
