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.

Research Questions

  1. How was pi discovered?
  2. How are circles used in technology?
