Answer:
25 in ^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 ( 4.3)^2
A =58.0586
The take the fraction of the circle that is shaded
A circle is 360 degrees
155/360
155 /360 * the  total area = area shaded
31/72 * 58.0586 = 24.99745278 in ^2
Rounding yields 25 in ^2

Answer:
The correct option is D)  .
 .
Step-by-step explanation:
Consider the provided cubic function.
We need to find the equation having zeros: Square root of two, negative Square root of two, and -2.
A "zero" of a given function is an input value that produces an output of 0.
Substitute the value of zeros in the provided options to check.
Substitute x=-2 in  .
 .

Therefore, the option is incorrect.
Substitute x=-2 in  .
 .

Therefore, the option is incorrect.
Substitute x=-2 in  .
 .

Therefore, the option is incorrect.
Substitute x=-2 in  .
 .

Now check for other roots as well.
Substitute x=√2 in  .
 .

Substitute x=-√2 in  .
 .

Therefore, the option is correct.
