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

There are a total of 84 students in a drama club and a yearbook club. The drama club has 16 more students than the yearbook club
vodomira [7]
Y = yearbook club
d = drama club

y + d = 84
d = y + 16

now we sub y + 16 in for d in the first equation
y + d = 84
y + (y + 16) = 84
2y + 16 = 84
2y = 84 - 16
2y = 68
y = 68/2
y = 34 <=== yearbook club students

d = y + 16
d = 34 + 16
d = 50 <=== drama club students
