The pi we are talking about is not the delicious desert. This pi is a //iratinal// number which means it is a non-terminating(dosen't end) non-repeating (doesn't repeat)decimal. Pi is the ratio of the circumfernce of a circle to its diameter. Pi always stays the same number no matter how big or small the circle is.
 * What is pi?**

Pi comes from the Greek letter **π** which we pronounce as our letter 'p' that means perimeter.
 * What language does pi come from?**


 * What formulas use pi?**
 * 1) C=2πr cicumfernce of a circle
 * 2) A=πr² area of a circle
 * 3) V=1/3πr²h
 * 4) V=πr²h
 * 5) S=2πrh+2πr²

Pi is caculated when you divide the circumferance of a circle by its diameter.
 * How do you caculate pi?**

Pi is very old. The Egyptians and Babylonians knew about the ratio pi, but they did not know the value as well as we know it today.They thought it was a little larger than 3. The Babyloians estimate of how much pi was was closer to pi than the Egyptians. The modern symbol for pi was used in 1706 by William Jones. Archamedeas and Syracuse in the third century BC. Zu Changzhi did the same thing as Archimeadies without knowing about Archamedieas work.
