The tangents drawn at the ends of a diameter of a circle are

• Intersecting

• Prallel

• Coincident

• None of the above

From the figure from a point P which is at a distance 13 cm from the centre O of a circle of radius 5 cm , the pair of tangents AP and BP to the circle are drawn. Then the area of the quadrilateral PAOB is
