I made a video recently in an attempt to explain what pi is to a student who lives in a different Country. If anyone has a better way to explain it or can give feedback on how I can improve my explanation then I’d greatly appreciate it.

Once you understand what pi is and you understand the formula for the circumference of a circle, this applet should help with understanding the formula for the area of a circle.
