According to internet sources "pi" has a relationship to the word "Perimitros" in Greek.
This makes logical sense as pi has a deep connection to the circumference of a circle which is actually the "perimeter" of a circle. If the diameter of a circle is 1, its perimeter (also known as circumference) is equal to pi.
You can approach pi using numbers as such...
\(512\sqrt { 2-\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2 } } } } } } } } }\)
*Plug this one into your calculator.
