Area is pi r^2. So it's actually 80*80*3.14=6400*3.14 ~ 20000. If you're talking squares, that'd amount to ~800 (since each is 25 square feet). But anything that focuses exclusively on the count will ignore that a bunch of those are partial squares that you need a method for determining whether it's in or out and means it touches significantly more than that 800 squares. Also, Pathfinder generally does diagonals on a 5,10,5,10... basis which affects how corners land.
