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

All of the total number of spectators at a circus show 1/4 or men 2/5 of the remaining number of spectators are women there 132

kkurt [141]

Answer:

There are 198 children at the circus show.

Step-by-step explanation:

Let the total number of spectators be 'x'.

Given:

Number of men = $\frac{1}{4}$ of the total number

Number of women = $\frac{2}{5}$ of the remaining number.

Also, number of women = 132

Number of men = $\frac{1}{4}\ of\ x=\frac{x}{4}$

Now, spectators remaining = Total number - Number of men

Spectators remaining = $x-\frac{x}{4}=\frac{4x-x}{4}=\frac{3x}{4}$

Now, number of women = $\frac{2}{5}\times \frac{3x}{4}=\frac{6x}{20}$

Now, as per question:

Number of women = 132. Therefore,

$\frac{6x}{20}=132$

$6x=132\times 20$

$x=\frac{2640}{6}=440$

Therefore, the total number of spectators = 440

Also, number of men = $\frac{x}{4}=\frac{440}{4}=110$

Now, total number of spectators is the sum of the number of men, women and children.

Let the number of children be 'c'.

Total number = Men + Women + Children

$440=110+132+c\\440=242+c\\c=440-242=198$

Therefore, there are 198 children at the circus show.
