cord is at a distanceof 24 cm from O. Draw a perpendicular OD on AB , thus ,

OD= 24 cm.

In right angled triangle. ODB

OB^2 = OD^2+ DB^2

r^2 =(24)^2+(AB/2)^2 = 576+(14/2)^2

r^2 = 576+ 49=625

r = √625. =25 cm. Answer.

It's A. All you have to remember here are your rules of translations. If there is side to side movement within a parabola it will be indicated within a set of parenthesis with the x coordinate. If there is no set of parenthesis with the x there is no side to side movement. The quantity $(x+3) ^{2}$ tells us that the vertex has moved left 3 units.
