Value of Pi in Maths - Definition, Forms & Solved Examples (2024)

The value of Pi (π) is the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159. In a circle, if you divide the circumference (is the total distance around the circle) by the diameter, you will get exactly the same number. Whether the circle is big or small, the value of pi remains the same. The symbol of Pi is denoted by π and pronounced as “pie”. It is the 16th letter of the Greek alphabet and used to represent a mathematical constant.

Value of Pi (π) in Fractions

The pi value in fraction is 22/7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations. ‘π’ is not equal to the ratio of any two number, which makes it an irrational number.

Frequently Asked Questions

What is the exact value of Pi and why?

The pi is an irrational number and does not have an exact value. In general, the value ofπ is considered as 3.14 or 22/7 for various mathematical calculations.

What is Pi and how it originated?

Pi is a mathematical constant which represents the ratio between the circumference and the diameter of a circle. The pi value was first calculated by Archimedes of Syracuse. The symbol π was first popularized by Leonhard Euler in 1737.

What is the formula for calculating pi?

The pi is a ratio and is obtained from a circle. If the diameter and the circumference of a circle are known, the value of pi will be asπ =Circumference/ Diameter.

As a seasoned mathematician and enthusiast with a deep understanding of mathematical constants, I find the topic of Pi (π) to be both fascinating and foundational in the realm of mathematics.
