The circle centered at (2,-1) and with radius 4 intersects the circle centered at (2,8) and with radius sqrt(14) at two points A and B. Find AB^2.

AB^2 = 22.

I don't understand how they can intersect.

Their centers are on a vertical line 9 units apart (from -1 to 8).

The first circle has a radius of 4 while the second circle has a radius less than 4.

How can they intersect?
