Answer: 13.96 in²

<u>Step-by-step explanation:</u>

radius (r)

d = 2r

16 = 2r

8 = r

angle in radians (θ)

$\frac{180}{\pi} =\frac{25}{\theta}$

180(θ) = 25(π)

θ = $\frac{25}{180}\pi$

θ = $\frac{5}{36}\pi$

Area (A)

A = $\frac{1}{2}$ r² θ

= $\frac{1}{2}(8)^{2}(\frac{5}{36}\pi)$

= $\frac{40}{9}\pi$

= 13.96

Answer: 12π

<u>Step-by-step explanation:</u>

s = rθ

= 60 $(\frac{\pi }{5})$

= 12π

Answer: 22.440 cm²

<u>Step-by-step explanation:</u>

A = $\frac{1}{2}$ r²θ

= $\frac{1}{2}$ (10)² $(\frac{\pi} {7})$

= $\frac{50}{7}\pi$

= 22.440

Answer: 270°, 630°, -450°, -810°

<u>Step-by-step explanation:</u>

positive: -90 + 360 = 270

270 + 360 = 630

negative: -90 - 360 = -450

-450 - 360 = -810

Answer: $\frac{3\pi} {4}$

<u>Step-by-step explanation:</u>

$\frac{19\pi} {4} - 2\pi$

= $\frac{19\pi} {4} - \frac{8\pi} {4}$

= $\frac{11\pi} {4}$

$\frac{11\pi}{4} - 2\pi$

= $\frac{11\pi} {4} - \frac{8\pi} {4}$

= $\frac{3\pi} {4}$

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.

Sidana [21]

Answer: inferential

Step-by-step explanation: inferential statistics help us to make predictions ( that is, inferences) from that data. With inferential statistics, you take data from samples and make generalizations about a population.

Also, inferential statistics allow us to reach conclusions that extend beyond the immediate data alone

In this question, the survey reports on a sample of the country's population that make an inference to the population. It is therefore an inference statement.

One building is 60 stories tall, and a second building is 48 stories tall. What is the ratio, in simplest terms, of the number o

Kobotan [32]

Answer:

Ratio is : 5/4 or 5 : 4

Step-by-step explanation:

The ratio of the number of stories in the first building to the number of stories in the second building :

60 : 48 or 60/48

Both numbers have 3 and 4 as common factors. So

3 * 4 * 5 : 3 * 4 * 4

5 : 4 is the ratio in the simplest terms striking of the common factors.
