It is A x= -9 I just did the assignment so yes, this means it is -9 I hope m answer helps you out.

Answer: A
Step-by-step explanation:
I don’t know spanish sorry
The correct answer is
<span>2) Calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply the area of the circle by this fraction.
area of the circle is calculated by;
area = </span>πr² , where r- radius of circle
<span>the central angle of a circle is 360</span>°. Area of the circle is calculated for central angle of 360°.
<span>Sector is when 2 arms/ radii enclose a central angle between them.
area for 360</span>° = πr²
<span>area for 1 </span>° = area/ 360
<span>area for central angle of sector = area * angle/ 360
the angle of sector is divided by 360 and taken as a fraction .this fraction of the total area of the circle is taken as the area of the sector.
