A certain circular area has its center at point P and has [#permalink]  27 Dec 2007, 07:26
A certain circular area has its center at point P and has radius 4, and points X and Y lie in the same plane as the circular area. Does point Y lie outside the circular area?

1. the distance between point P and point X is 4,5.
2. the distance between point X and point Y is 9.

1 is not sufficient
2 is not sufficient

1+2 are sufficient to say that Y is outside the area, since the distance from X and the farther point on the circumference is 4,5+4=8,5.

C is right
