<PRE><B>Question 467346</B>
If a recipe requires 100 grams of grated motzarella for a 25cm pepperoni pizza, how much cheese will be neede for a 40inch pizza? (the measurement given here is the diameter of the pizza.)
------------------------
Area of a 25cm pizza = 25*pi sq. cm.
----
Area of a 40 INCH piaza is 40*pi sq inches.

Note: I have a feeling you did not post 
this problem correctly.
