HELP me with These questions

Feliz [49]

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.

Which is the best estimate for the sum of 3/8 and 1/12¿

SashulF [63]

Estimating is an educated guess, so 3/8 is just less than half, and 1/12 is just a bit more than 0. So you could estimate that 3/8 + 1/12 = roughly 1/2

<span> if you add 3/8 and 1/12 you get 11/24</span>

Gwendolyn was physically present in the United States for 96 days in 2019, 198 days in 2018, and 66 days in 2017. Under the subs

Svetradugi [14.3K]

Answer:

173 days

Step-by-step explanation:

The formula for substantial presence test is;

SBT = (Total of number of days present in the current tax year) + (1/3)(number of days in the year that was before the tax year) + (1/6)(number of days in the year that was two years before the tax year)

From the question, present tax year is 2019 and number of days is 96 days.

Year before tax year is 2018 and number of days is 198 days

2 years before tax year is 2017 and number of days is 66 days.

Thus;

SBT = 96 + ((1/3)198) + ((1/6)66)

SBT = 173 days
