Pi Day 2019

The first annual Kilbreda Pi Day took place on March 14. During the preceding weeks the excitement for the day was building. The Pi song was played during Mathematics lessons and homerooms. Rumours were circulating of a student who could recite Pi to many many decimal places.....but, what is Pi?

Pi is the ratio of a circle's circumference to its diameter. ... So, for any circle, dividing its circumference by its diameter will give you the exact same number: 3.14159…or Pi.

Pi is also an irrational number, which means that its value cannot be expressed exactly as a simple fraction. This also means there is no repeating pattern in the digits. This makes it even harder to remember any of the sequence.

When the day arrived we gathered in the Maths Resource Room. There was a sense of expectation. Students taking part had their supporters for encouragement.

So, we began, the first student managed 10 correct digits, which was a great effort. The next student managed 48. Then we had 54, 55, and 60 from a Year 7! We were all very impressed

Finally our last competitor stunned us all with an incredible 250 decimal places. What an outstanding achievement!

250 decimals places of Pi is given below so you can see just how immense this achievement was

Our prizer winners were:

Belinda Gale - 10 decimal places
Sofia Bondarenko - 48 decimal places
Skye Hornidge - 54 decimal places
Brooke Saunders - 55 decimal places

And the amazing winner was...

Bridgette Turner - 250 decimal places

Congratulations to everyone who took part. What can we expect in 2020, the gauntlet has been thrown down!
