Answer: 13.96 in²

Step-by-step explanation:

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: 22.440 cm²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

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

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

= 22.440

Answer: 270°, 630°, -450°, -810°

Step-by-step explanation:

positive: -90 + 360 = 270

270 + 360 = 630

negative: -90 - 360 = -450

-450 - 360 = -810

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

Step-by-step explanation:

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

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

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

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

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

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

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