Quandaries
and Queries 

Hi. I'm a 7th grader at Lakeside Middle School. And I was wondering if you can answer a question for me for my math project. I'm doing a project on pi, and my teacher said to ask an expert like you to ask about how you would use the subject, pi, in real life usage. How would you use pi in real life usage? I know it's just a simple question, but I hope you would answer my question for my project. Thank you. 

Hi, Here are three questions that we have received that involve pi and are from nonschool situations. One concerns the amount of water in a pipe the second the diameter of a pipe and the third about a roll of paper. Pi appears in many places. Every time you need to find the area of a corcle or the volume of a balloon you need pi. Almost every calculation you make with a circle involves pi. Penny
