Funny - I was just going to reply "don't worry about it - it's more than you'll ever be able to make".
Reminds me of a funny story my son told me - he was taking a geometry test when all of a sudden he bursts out laughing. The teacher just says "looks like someone got the joke and will get an A".
The question: Write the expression for the volume of a circular shaped food with height 'A' and radius "Z".
The formula for volume is: π·(radius)2·(height)
This makes the answer: pi·z·z·a
