Re: how many coins?

Jim:
Can you prove this?
The area of the rectangle is 2000 cm^2, and the circle is pi/4 cm^2. So, if the coing was "soft", we can fit 2000 / (pi/4) ~ 2500. The question is, off setting the coins will really reduce the waste.
By the way, the name Graham sounds familiar. Does anyone have a reference?
