Meaning of the constant Pi
Test your understanding of meaning of the constant Pi by practicing it! Work through the below exercises to use it in practice.
🎙️
What does 'Pi' mean in the geometry of circles?
🎙️
For every circle, no matter its size, the distance around is a bit more than 3 times the distance across
🎙️
In fact, it's 3.14159, and continues forever
🎙️
So we just use a Greek letter, called Pi, to represent this number that is a bit more than 3
🎙️
All Pi is is the ratio of a circle's circumference to its diameter, and you'll use that a lot when working with circles
