Hey mr cox
its chris buettner from 2/3 period
i looking forward to this year
the answer to the problem is 54,000
imagine a circle in a square
the square has sides of 500
the sircle has a radius of 250
find the area of the cicle and which is 196,250
find the area of square which is 250,000
then subtract 196,250 from 250,000 which equals 53,750
and then round it to the nearest thousandth which is 54,000
