A friend of mine asked me the following question. If you roll a piece of 8-1/2 x 11 paper into a cylinder

8-1/2inches tall or a cylinder 11 inches is the enclosed volume the same? Doing "Gestimation Math" I came to the answer of "No". That is the correct answer. I will let you play with a calculator and get the percent of difference. So far so good.

Now, today driving from Kirkland to Kelso and back we saw a large number of Tank Trucks. So my question is why were all the trucks hauling petroleum equipped with oval tanks? Those hauling Milk were using cylindrical tanks. The compressed gas ones were understandably a cylinder as well. Those hauling bulk Cement are some goofy shape and some unlabeled ones were a kind of cylinder with a sag in the middle of the bottom.

After I get some answers I will explain why the question.

Thanks in advance

Pete
