Answer:
9 boxes
Step-by-step explanation:
[tex]Area=\pi r^{2}[/tex]
Since 1 ft= 12 inches then with diameter of 12 ft, radius becomes 6 ft and converted to inches it's 6*12=72 in
[tex]Area=\pi\times 72^{2}=16286.01632 in^{2}[/tex]
Area of 1 tile= 9*9=81
Number of tiles= [tex]\frac {16286.01632 }{81}=201.0619298 \202 tiles[/tex]
Number of boxes= 202/25=8.08 boxes hence 9 boxes
