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

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

Anon25 [30]

Answer:

She can cut 24 ribbon from this long strip.

Step-by-step explanation:

Given that,

Bella needs identical strips of ribbon measuring 3.5 feet each.

She has 85 feet of ribbon.

3.5 feet is length of 1 ribbon.

1 feet is length of $\frac{1}{3.5}$ ribbon

85 feet is length of $\frac{1\times 85}{3.5}$ ribbon

≈24.28

$\frac{85}{3.5}=\frac{85\times10}{35}=\frac{85\times2}{7}=\frac{170}{7}$

7) 170(24

_______

______

So, she can cut 24 ribbon from this long strip.
