Pi Day Activity for proving the circumference formula. Also includes Pi posters. This is a hands-on activity for using the decimal form of Pi (3.14) to compare the length of a circle’s diameter to its circumference. The Pi ratio can be used to lead to the rediscovery of the circumference formula. It might sound complicated but this activity makes it so easy to understand because it allows for a concrete understanding if diameter, Pi and circumference. It is created for two different sizes of circles; for the 7cm diameter circle and for the 14cm diameter circle. All dimensions are in cm (metric) units. It also contains Pi posters which show the many different ways of representing Pi.
