Answer 12

One possible interpretation of pi is the ratio of the circumference to the diameter.
If we took a string and placed it over the diameter and measured that length, and then wrapped it around the circumference and measured; we could take the quotient of the two in order to approximate this ratio. :)

With more math: \(C = \pi d \to \frac{C}{d} = \pi \) by a division.

Answer 15

This is how I like to interpret pi, it's a little silly though :)
If you think of a big square, 2 by 2.
Break it up into 1 by 1 squares as I have done.
Soooo the big square has area of 4.

You'll notice that the area of the circle is less than that of the squares, it ends up filling a little more than 3 of those squares.

If you have a circle of Radius 1, (which is what the picture is showing), Then the area is pi.\[\large A=\pi r^2\qquad \rightarrow \qquad A=\pi \cdot 1^2\]Just something to think about :)
