A circular playground for a daycare center is to be covered with square tiles that are 9 inches on each side. The circle has a d

nydimaria [60]

Answer:

9 boxes

Step-by-step explanation:

$Area=\pi r^{2}$

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

$Area=\pi\times 72^{2}=16286.01632 in^{2}$

Area of 1 tile= 9*9=81

Number of tiles= $\frac {16286.01632
}{81}=201.0619298
\202 tiles$

Number of boxes= 202/25=8.08 boxes hence 9 boxes

This simplifies to

$165.6 \degree$
