                             1st Question

            What is the value of Pi (π)?

Team 1:Maria Agrapidi, Greece

The value of π (pi) refers to the ratio of the circumference of a circle to its diameter in Euclidean geometry. It is a mathematical constant that appears in many areas of mathematics and science.

                           2nd Question

         How is Pi defined as a                  mathematical constant?

Team 1: Gabriela, Romania

Pi (π) is defined as the mathematical constant representing the ratio of a circle's circumference to its diameter. This ratio is the same for all circles, regardless of size.

                            3rd Question

    Why is Pi an irrational number?

Team 1:Ismail, Turkey

Why is π irrational?

Intuition:

Because circles and geometry involve continuous, infinite processes, the ratio π cannot be neatly expressed as a fraction. It’s inherently "unruly" and infinite in decimal form.

                            4th Question

What is the numerical value of Pi?

Team 1:Angelica, Italy

The numerical value of π (Pi) is approximately:

3.14159

For most purposes, using 3.14 or 22/7 as an approximation is sufficient. However, π is an irrational number, meaning its decimal representation goes on forever without repeating. Some more digits of π are:

3.1415926535 8979323846 2643383279...
