2 A Warm Slice of Pi By: Michael Gross Majeed Mogharreban Anjan Tibrewala Daniel Raino

3 Definition Pi is the constant ratio of the circumference to the diameter of a circle

4 History of π Bible – ratio = 3 In the Egyptian Rhind Papyrus, which is dated about 1650 BC, there is good evidence for 4(8/9)2 = 3.16 as a value for π The first theoretical calculation seems to have been carried out by Archimedes of Syracuse ( BC). He obtained the approximation 223/71 < π < 22/7.

5 Chronology

7 Pi Record Yasumaga Kaneda got 536,870,000 digits in August It took 67 hours and 13 minutes on a Japanese supercomputer.

8 Applications Area of circles Volume of spheres Cylinders Cones Round stuff Slicing pie Ice cream!
