pi day

It's celebrated on march 14 because if you like math pi is rounded to 3.14 and if you think you can see that march is 3 and the day is 14 so 3.14. Pi day is just a fun day for family and friends. If you the diameter of the circle, you can also caculate it's area by squaring the radius of the circle and multiplying it by pi. By: Trevor Becker
