Project Time Frame
This project explores the properties of circles and the nature of pi.
The goals of this project are:
- To demonstrate the nature of pi in an easily understandable way.
- To encourage further interest in the field of mathematics.
Materials and Equipment
- Computer with Internet access
- Color printer
- Digital camera
- Typical office/hobby/hardware/craft supplies (paper, poster board, glue, wood, etc.)
All materials can be found in your home, at local stores, or on ebay.
Pi is a number whose value is approximately 3.141593... The digits of pi go on and on forever, and competitions are often held to see who can recite (from memory) pi to the farthest digit. Pi is used in the measurement of circles. For instance, the circumference of a circle is equal to its diameter times pi.
- How was pi discovered?
- How are circles used in technology?
