How to measure the value of PI with simple equipment and scale?
How to calculate the value of Pi? In a circle with radius r, make an inscribed regular hexagon (as shown in the figure). In this case, the side length of a regular hexagon is equal to the radius r of the circle. Therefore, the circumference of a regular hexagon is equal to 6R

A few divided by a few is the PI
The PI is an irrational number and can not be expressed as M / N (M and N are positive integers, which is applicable to all rational numbers). Therefore, it is impossible to be equal. There are two fractions very close, i.e. approximate ratio 22 / 7 and density ratio 355 / 113
If the absolute value of a divided by a equals 1, what number is a
By | a | a = 1,
(1) When a > 0, | a | a = a, | a △ a = 1 holds
(2) When a < 0, | a | = - A, ν - a △ a = - 1,
If not, give up
Why is pi equal to perimeter divided by diameter instead of radius?
The so-called "rate" is the ratio of two numbers. When you measure the circumference of a circle, what can you compare with it? The most convenient one is diameter. For example, how do you get the radius of a circular iron plate, or is the diameter convenient? You can't measure the radius of a tree or a cylinder all of a sudden, and so on, For convenience, this is called PI. Of course, if you have to compare the circumference of a circle with the radius, the "ratio" obtained is about 6.28, which is the same in application
Why is diameter times PI equal to perimeter?
I just learned it today,
Because a semicircle is divided into a rectangle, its radius is the width of the rectangle, and its semicircle circumference is equal to the length of the rectangle. Because of the area formula of the rectangle, C = π times r squared, which is C = π times r times R
