If the side of the square is 12 cm, then the radius of the circle is half of that, or 6 cm. The circumference of a circle is 2*Pi*r. Substituting r, we get

$$2\Pi6cm=12\Pi\approx37.7cm$$

That was a creative way of making the symbol for pi! For future reference, use /pi in Latex to get the desired symbol. It looks like this:

$$\pi$$
