What is Pi? How does PI come from?
PI, generally expressed by π, is a universal mathematical constant in mathematics and physics. It is defined as the ratio of the circumference to the diameter of a circle. It is also equal to the ratio of the area of a circle to the square of its radius

Is pi a number in the set of positive numbers
yes
Although Pi is an infinite decimal, it is still a positive number
So it's certainly a number in the set of positive numbers
Is π (PI) a fraction?
According to the strict definition, this is not a fraction. Fractions are all rational numbers
What is pi expressed as a fraction?
In 1573, Otto, the German, has only an approximate value of the ratio of circumference. He used the results of Archimedes 22 / 7 and Ptolemy's 377 / 120 to "synthesize" with the addition method: (377-22) / (120-7) = 355 / 113
What is the value of PI, write it out as much as possible. What is the score closest to Pi?
PI refers to the ratio of circumference to diameter of a circle on a plane. It is represented by the Greek letter π (read "Pai"). In ancient China, there are names of the ratio of circumference, circumference, and so on. (in general calculation, π is converted into an infinite non cyclic decimal of 3.14)
How is the PI calculated?
Use the circumference of the circle to compare the diameter of the upper circle. Of course, the more accurate the circumference and diameter of the circle, the better
How many places can PI be calculated now
French Software Engineer Fabrice bellard has claimed he has calculated 2700 billion decimal places, breaking the Guinness world record of 2577.9 billion decimal places calculated by Japanese scientists using supercomputers last year
How is the PI calculated?
It is defined as the ratio of the circumference to the diameter of a circle. It is also equal to the ratio of the area of a circle to the square of its radius
