## Answer :

Pi is called pi because pi is the first few letters in perimitros (a Greek word).

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...

[tex]512\sqrt { 2-\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2+\sqrt { 2 } } } } } } } } } [/tex]

**Plug this one into your calculator.*
