Formula for the area of a quarter circle: A = (pi x r^2) / 4

A = (pi x 2^2) / 4

A = (pi x 4) / 4

A = 4pi / 4

A = 1pi = 3.14 square miles

Hope this helps! :)

A questionnaire has determined that 20% of the residents of Flaugamuck County own an iPod. Furthermore, 80% of these iPod owners

nydimaria [60]

Answer:

P = 7.14%

The percentage of those 30 years or older that own an ipod is 7.14%

Step-by-step explanation:

Given;

Percentage of ipod owners Pi = 20%

Percentage who don't own ipod Pd = 100-20 = 80%

For age 30 or older;

Percentage of ipod owners who belong to this group

Po = 20% of Pi

Percentage who don't have an ipod but belong to this group Pu = 100-35% = 65% of Pd

The percentage of those 30 years or older that own an ipod is;

P = Po/(Po+Pu) × 100%

Po = 20% of Pi = 20% of 20% = 0.2×20 =4%

Pu = 65% of Pd = 65% of 80% = 0.65×80% = 52%

Substituting the values;

P = 4/(4+52) × 100%

P = 7.14%

Answer:

C p^2 - p - 5

Step-by-step explanation:

Combine like terms (p^2, p, numbers)

4p^2 - 3p^2 = p^2

-5p + 4p = -p

3 - 8 = -5

A company makes paper labels for paint cans. As shown below, cach can is in the shape of a cylinder with a height of 9 cm and a

IgorC [24]

Given:

Height of cylinder, h = 9 cm

Radius, r = 3 cm

Total amount of paper the company has = 8138.88 cm²

Let's find the number of labels that can be made given that the label covers only the side.

Here, we are to apply the formula for the surface area of a cylinder.

We have:

$SA=2\pi rh+2\pi r^2$

The 2πr² represents the area of the top and bottom circle of the cylinder.

Since the label covers only the side, we are to exclude the 2πr².

Hence. we have:

$SA_{label}=2\pi rh$

WHere:

r = 3 cm

h = 9 cm

Thus, we have:

$\begin{gathered} SA_{label}=2*3.14*3*9 \\ \\ SA_{label}=169.56\text{ cm}^2 \end{gathered}$

Now, the number of labels they can make is:

$\begin{gathered} \text{ number of labels = }\frac{8138.88\text{ cm}^2}{169.56\text{ cm}^2} \\ \\ \text{ number of labels = 48} \end{gathered}$

Therefore, the company can make 48 labels.

ANSWER:

48 Labels
