How to order pizza?
1) Decide what kind of pizza I want.
2) Pull out all the fliers we got and check netpincer.hu
3) Look for sizes/prices of desired pizza.
4) Since sizes vary, calculate area of actual pizza in cm2 (use 3,14 x r2 where r is the radius of the circle, that is half of the size of the pizza on the paper)
5) Divide price by area.
6) Compare results.
7) Order cheapest.
