Your post contains neither a figure nor a description of the figure, so we have no idea what area is marked "Aa".

Thanks for providing a link to a diagram in you thank-you note to me.

But I already knew what the figure looked like. What I didn't know, and still don't, is what part of the figure is the area "Aa".

Hey, it is really interesting to me to know how seven circles of the same radius
can be tangent " to each other " on a plane.

Could you provide a link, a picture, a sketch or a reference ?

As a bonus, I promise to send you 1 (one) US dollar in response . . .

I got a response from you pointing to the link
https://etc.usf.edu/clipart/42900/42921/circle-27_42921.htm

But notice, that the 7 (seven) circles of radius of 3 cm in this plot DO NOT TANGENT " each to other ",
so yours wording description is INCORRECT.

It is PRECISELY what I wanted to make sure, that your description is incorrect.

It is incorrect, because it describes a situation which NEVER MAY HAPPEN.

Therefore, I will not send you my one US dollar.

I can not spend my money paying for incorrect descriptions . . .
