Data Suff.
See attachment for figure, please.
In the figure, points A, B, C, D, and E lie on a line. A is on both circles, B is the center of the smaller circle, C is the center of the larger circle, D is on the smaller circle, and E is on the larger circle. What is the area of the region inside the larger circle and outside the smaller circle?
(1) AB = 3 and BC =2
(2) CD =1 and DE = 4
Formal Answer: E
My Answer: The information provided for the AB line allows me to calculate the area of the small circle. The information provided for the AB and BC line (radius of large circle) allows me to calculate the area of the large circle. I selected answer A.
