180 Days of Ideas for Discussion in Math Class. (as of 9July2014, we're in overtime!)
10000 random dots.2175 red dots.7824 blue dotsFind the missing dot? Sorry.Actually, I think we're looking at the fraction pi/4 since the circle has area pi*r^2 and the square has area (2*r)^2 = 4*r^2. The circle takes up pi/4 of the total area, and pi/4*10000 = 7854 ish.Happy pi day!
You're missing 1 dot. I only count 9999.
There's about 150 covered up by the white rectangle, ironcates. Your counting skills ... FAIL.
