Extention Maths

This week for maths we have been looking at the area of different shapes like Polligones triangles and circles

To get the area of the a circle to first to get the center of the circle to the outsides length. For example 4.25m
So To work this out you have to go A= PI times 4.25 times 4.25

So pi is 3.14159265359

So 3.14159265359 times 4.25 equals 13.3517687778 so to make it easier lets have it at 13.35 then times 13.35 by 4.25 So that equals 56.7375.

So that is how you get the area of a circle if you like this piece of writing it that comment button and tell me
