In the xy-plane, point (r, s) lies on a circle with center at the origin. What is the value of r^2 + s^2?

(1) The circle has radius 2.
(2) The point (v2, -v2) lies on the circle.

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.

I think it's A
Question is really asking what the radius is. A gives that. B is out of scope

i got A too.

with radius 2 --> that means the other two sides of the triangle inside the circle have to be 2^1/2 and 2^1/2 (since the hypotenuse is 2 (a^2+b^2=c^2) so:

squaring the two sides gets 2+2 = 4

i think this is right.
