x = r * sinA / (1 - sinA)
(Math teachers told my daughter yesterday she'd need sin and cos someday
so she came home and made me give her three examples of how/why I've
used it with flash -- if anyone has any good ones besides eyes following
mouse, moving object on a line relative to horizon, 3d, making a dial
spin, I'd be happy to have more to pass on to her)

Hi List,
I'm trying to figure out what radius to make n number of circles fit
around a circle of radius r. Several diagrams later I'd got it down to:
sinA = x / (x + r)
Where A is half the angle required by each circle ((360/n)/2), x is
the radius we're looking for and r is the radius of the circle in the
middle. Sadly my maths just aren't up to solving for x...
Maths teachers are always teeling you you'll need algebra one day...
Luckily there's a Flashcoders :P
Many thanks,
David
