Answer 5

Let me show you how i got it.

Answer 6

radius = 6 ft = 72 inches
----------
Area = pi*72^2 = 5184*pi sq in
----------------
Area covered by a box of tiles = 9^2*25 sq in

Answer 7

boxes need = [5184*pi]/[81*25] = 8.0425 boxes
------------------
9 boxes needed, because 8.0425 is more than just 8.
