Unsure of what you mean by "reference number."
I do recognize that 11pi/9 is in quadrant III. I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.
That difference is 2pi/9.
Answer:
Well, Those best choice will be is: A. The area of a circle depends on the length of the radius.
B. The area of a sector depends on the ratio of the central angle to the entire. D. The area of the entire circle can be used to find the area of a sector. E. The area of a sector can be used to find the area of a circle. Hope This Helps!!~
