Re: circle geometry problem

Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: circle geometry problem

hi classof2020

Welcome to the forum.

Hopefully this diagram will show you how to do this.

The yellow shape is a  square.  There are 7 of those.   The red sectors have angle 360/7 so if you fit 7 of them together you will get a perfect circle.
