What is pi?
What is pi?
Pi is the special name we give to the ratio of the circumference of a circle divided by its diameter.
We use the Greek letter π as a short cut.
π = 3.14159265358979323846…..
The digits go on and on with no pattern.
π has been calculated to over sixty trillion decimal places and still there is no pattern to the digits.
π is an irrational number which means it cannot be written as a fraction.
Task 1 - Calculating with pi
Task 1 - Calculating with pi
Use the Geogebra applet, Connecting the diameter and circumference of a circle, embedded below, to measure the diameter and circumference for different sized circles.
Change the diameter of the circle by moving the blue centre point.
Move the red slider to investigate the connection between the circumference and diameter.
Use the information from the Geogebra applet to complete the Investigating pi activity.
