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

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

D.

Since all the points lie on one line, we can calculate radii of both circles, which is necessary to find (area of larger circle - area of smaller circle)

The questions seems intresting. Can you post the picture/graph?

I believe the figure should look like this. (Excuse my drawing skills though)

It is possible that the smaller circle is outside the larger circle but then the question wouldnt be asking

Your picture looks realistic.

D. If your picture is the same as the original one, then either statement sufficiently provides the redius for each circle.

What we need is redus of the circles.

How would you find out the radius of smaller circle from just stm 2 itself

adius of small circle = AD/2.

Now, AD = CE - CD.
