Answer:

Step-by-step explanation:

Note that

(g - $\frac{1}{g}$ )² = g² - 2 + $\frac{1}{g^2}$ = 51 - 2 = 49

Take the square root of both sides

g - $\frac{1}{g}$ = $\sqrt{49}$ = 7 ← the positive value

What is the arc length of the shaded region to the nearest tenth?

Maslowich

Answer:

285

Step-by-step explanation:

The total amount of degrees in a circle is 360, we know that the un-shaded portion of the circle is 90 degrees this means that the shaded portion has 270 degrees.

We also know that the area of the circle is $\pi r^{2}$ but we are finding a portion of that, therefore we would need to multiply it by $(\frac{270}{360} )$ . The radius is also given which is 11.
