Basically all you have to do is find the area of both circle and then minus the non-shaded area from the shaded area. So the equation to find the area of a circle is πr^2 so the radius for the non-shaded shaded is 1.2 square that then mutiply it by π ,(pi). Next the radius for the whole circle is 3.5 so square that then mutiply it by π. Next just subtract the two, non-shaded to shaded area.

Answer:

$x=-243$

Step-by-step explanation:

The equation is

$-3^{-5}=\frac{1}{x}$

Solve for x

we know that

$-3^{-5}=-\frac{1}{3^{5}}=-\frac{1}{243}$

substitute

$-\frac{1}{243}=\frac{1}{x}$

so

$x=-243$
