When you draw three circles of radius r such that all three are externally tangent, what is the area of the shape in the center in terms of r?

(In reply to re: A Bermuda triangle by Ady TZIDON)

I actually toyed with dispensing with a denominator,

but I think that my solution is more readable in this format:

Rē(2√3 - π)/2    
{ this does say R*R*(2√3 - Pi)/2  or R^2*(2√3 - π)/2}

 [also I do not need to use a * sign prior to the first bracket as that is implied  -   the "π" is Pi, inserted from the Format Toolbar within the comment editing section].
