PI Day preparation

By slopjong on March 11, 2011

Hey folks. Keep in mind that the glory PI Day is on next Monday. And this year I’ll bake some yummy pie again. As I’m that much creative it’ll be again either a citron or a tiramisu cake. LOL. I don’t like to say LOL but I thought it would be cool to say it. LOL. One attendee of my famous etching and soldering workshop said LOL every 5 minutes and because he was cool saying LOL must be cool. LOL.

Back to PI. Bake a tasty pie, measure PI and share it with your friends!

Is somebody interested in the competition “Coming the most close to PI”?

c_{cake} = 29.7cm *3-14cm =75.1 cm d_{cake} = 23.5 cm \pi_{cake} = \frac{circumference_{cake}}{diameter_{cake}} = \frac{75.1cm}{23.5cm} = 3.19 err = 1- \frac{\pi}{\pi_{cake}} = 1- \frac{3.14}{3.19} = 1- 0.98 =0.02

The error between the measured \pi_{cake} and \pi is only 2%.

Here is the exact \pi:
