## How to calculate the a volume of a cylinder

#### Saturday, September 12th, 2009 | Tips

Are your students battling to remember the formula of a cylinder? Try to illustrate it by means of a pizza (I must admit it is a rather flat cylinder!).

If the height of the pizza is **a**, and the radius is **z**, the formula to calculate its volume is:

Is it to 2pizza?

Very clever! I like it. Much more user friendly than saying volume of a cylinder is the area of a circle (which is pi x radius x radius) x height of cylinder.

As a non-mathematician may I ask, does it make a difference if you take off the pepperami and add asparagus instead??

All this pi stuff sounds completely IRRATIONAL and abSURD to me… or as my husband would say, TRANSCENDENTAL…

Kathy, if you use asparagus it should not make any difference to the formula at all … provided the height is not altered. However, it may make a difference to the waistline!

Ha ha… that’s funny! You obviously didn’t get the bit about pi being a transcendental number – that’s an irrational number that can’t be written as a surd…

Here is another spot that explains it pretty good, even has some calculators you can use too.
