The circle has center O and radius 50, and point P has coordinates (50,0). If point Q is on the circle, what is the length of line segment PQ?
(1) The x-coordinate of point Q is -30.
(2) The y-coordinate of point Q is -40.
[spoiler]OA - E. IMO - C...it says on the circle not anywhere in the circle...?can we assume it is on the boundary of the circle?[/spoiler]
Coordinates - circle

to find distance between any two points on the coordinate system we need x,y coordinates of both.
Q may be any where here & p may be anywhere just the coordinates of both are reqd to get the ans.
