$|3-x| = 8\\
x=-5\\
|3-(-5)|=8\\
|3+5|=8\\
|8|=8$
x = -5 or x=11
since |3 - 11| = |-8| = 8

What is the area of a sector of a circle with a radius of 6 inches and formed by a central angle that measures 90°?

trapecia [35]

$\bf \textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ \theta =90\\ r=6 \end{cases}\implies A=\cfrac{(90)(\pi )(6)^2}{360} \\\\\\ A=\cfrac{3240\pi }{360}\implies A=9\pi \implies A\approx 28.2743$
