Answer:

$3) \: \: 113 {ft}^{2}$

$4) \: false$

$5) \: 70 {ft}^{2}$

Step-by-step explanation:

3) Area of a circle is

$\pi \times {r}^{2}$

Where r = 6

Thus,

$area = \frac{22}{7} \times {6}^{2}$

$area = \frac{22}{7} \times 36$

$area = 3.143 \times 36$

$area = 113 {ft}^{2} \: (nearest \: whole \: number)$

4) False

Area of a circle is measured by the formula below:

$area = \pi \times {r}^{2}$

5) The formula for calculating the area of a rectangle is given thus:

$area \: of \: a \: rectangle = l \times w$

Where, l = 10ft; w = 7ft

$area = 10ft \times 7ft = 70 {ft}^{2}$

AlladinOne [14]

Answer:

$\frac{1024}{2025}$

Step-by-step explanation:

$\frac{3}{4}^{-4} = \frac{1}{\frac{3}{4}^{4} }$

(3/4)^4 = 81/256

1 ÷ 81/256 = 256/81

So;

$\frac{256}{81} * \frac{4}{9} = \frac{1024}{729}$

$\frac{1024}{729} / n = \frac{1}{9/25}$

$\frac{1024}{729n} = \frac{25}{9} \\\\n = \frac{1024 *9 }{25 * 729} = \frac{1024}{2025}$
