Re: Problems finding out the area of a 0.5mm circle.

Thanks for your help... So it seems that I divide 196250000000nm2 by
7850nm2, which equals 25million? But I am curious about tightpacking
and a slight bit unsure about the aforementioned simple division
because I worry about the diamond/star-like spaces between the circles:
that by ignoring them I don't get a realistic picture of how many small
circles I can fit in the big circle. The answer I get is that I can fit
25million 100nm diameter circles into a 500,000nm diameter circle. Do
you agree that 25million is correct? Would the answer be vastly
different with tight/close packing? How do I work out for close-packed?
And what about considering the gaps between the circles in normal
standard packing?

Please don't charge me with taking the micky or time-wasting. If you
think such a thing you are wrong. Yes, I am very literate regarding the
arts, psychology, philosophy etc., and as is common with emotionally
creative (artistic) types I am not very good at maths and I have never
really focused on learning any maths. No disrespect to creative
mathematicians or quantum physicists (emotional or otherwise) but
artistic people generally find maths very complicated and boring, thus
they tend to focus on 'other' more emotional paths of learning.

I am based in the UK and not the US and I post via my local library,
via the Google Groups web page.

I just wanted to know how many 7850nm2 circles fit into a
196250000000nm2 circle. If you aren't sure of the answer I'd be
grateful if you'd direct me to a place on the internet where I might
find the answer. I am only looking for some help and I didn't mean to
offend anyone. Sorry for asking lots of questions but when I research
something I find it is better to have an much info as possible.

Thanks for all your help and advice so far.
