PLEASE HELP ME FIGURE THIS OUT 1.......... WITH SCREENIES

Answer 1

Answer: $\frac{11\pi}{12}$

Explanation:

$\frac{59\pi}{12}$

Subtract 2π (which equals $\frac{24\pi}{12}$) until you get a value less than 2π.

$\frac{59\pi}{12}$ - tex]\frac{24\pi}{12}[/tex] = $\frac{35\pi}{12}$

$\frac{35\pi}{12}$ - tex]\frac{24\pi}{12}[/tex] = $\frac{11\pi}{12}$

Answer: 13.09

Explanation:

Area of a Sector = $\frac{\theta}{360}$* π r²

θ = 60, r = 5

A = $\frac{60}{360}$* π (5)²

  = $\frac{25\pi}{6}$

  ≈ 13.09

Answer: $\frac{1}{2}$

Explanation:

$\frac{11\pi}{3} - \frac{6\pi}{3} = \frac{5\pi}{3}$

Look for $\frac{5\pi}{3}$ (300°) on the Unit Circle to find that cos = $\frac{1}{2}$

Answer 2

\theta * r

\pi/3 * 5 = answer for #2
