what I learnt this week

Hey guys I know its kind of early in the week but HEY! I learnt something!!!!!!!
In maths class I learnt how to find the area of a circle!
To find it you do pi times radius squared
It stuck in my head by the worksheet we did afterwards, we had to cut out circles and fold it into quarters!
I have learnt alot of maths this year :)

This is the formula!!!!!!!!!

Completely random question but...

What college are you going to?
