What is nine Pai equal to

When Pai was 3.14, the answer was 28.26

If the absolute value of negative a is equal to negative a, then a ()

A ≤ 0, a is a non positive number
The answer is right!

If the absolute value of a is less than or equal to negative a, then a is

First of all, because it is the absolute value of a, at this time, the absolute value of a must be greater than or equal to zero, while the absolute value of a positive number is a positive number. The opposite number of a positive number is a negative number. A positive number will not be less than a negative number
The opposite of zero, the absolute value is itself, so a can be zero
If a is negative, then the absolute value of the opposite number is the same, so negative number is OK
To sum up, a is a non positive number

If AB is greater than 0, then the absolute value of a divided by a plus the absolute value of B divided by B plus the absolute value of AB divided by ab is equal to?

Equal to 0 or 2

It is known that: the absolute value fraction of a plus the absolute value fraction of B plus the absolute value fraction of C equals to 1. Calculate the absolute value of ABC divided by the absolute value of ab

When a / | a | a | is a > 0, a / | a | = 1; when a < 0, a / | a | = - 1
Also: A / | a | B / | B | C / | C | = 1
Two of the three numbers a, B and C are + 1 and - 1
In other words, two of the three numbers are > 0 and one is < 0
Therefore, ABC < 0
So | ABC | / ABC = - ABC / ABC = - 1

Who invented Pi? What is Pi?

In ancient and modern times, many people are devoted to the research and calculation of PI. In order to calculate the approximate value of PI, generations of mathematicians have contributed countless time and effort to this mysterious number. Before the 19th century, the calculation progress of PI was very slow. After the 19th century, the calculation of PI reached world records

The ratio of a circle's () to its () is called the PI, which is represented by the letter () with two decimal places, and the approximate value is equal to（ The ratio of a circle's () to its () is called the PI, which is represented by the letter (), with two decimal places reserved and the approximate value equal to ()

The ratio of the circumference of a circle to its diameter is called the ratio of the circumference to its diameter. It is expressed by the letter (π), with two decimal places reserved, and the approximate value is (3.14)
