Value of y= 18 and value of x= 9 root3
therefore answer is D
Since the area of a circle is π

, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so:

≈ 240°
240 degrees
<u />the answer may be 125 because 20 pieces of colored paper is only part and then the whole would be 125 because divided by is 5 so 25 times 5 is 125.
