A. the area of the sector is 360 - x/ 360 times the area of the whole circle.

b. the area of the sector is equal to . pi r^2/ x

c. the area of the sector is x/360 times the area of the whole circle.

d. the area of the sector is equal to. pi r^2/ 360 - x

C

Step-by-step explanation:

The area of the sector and the whole circle are proportional to the central angles.

a / A = x / 360°

a = (x / 360°) A

So the answer is C.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
