Find the length of the chord AB of the circle. Given radius OB=13 ,perpendicular length OP=12cm. 'O' centre of the circle.

Find the length of the chord which is at 12cm distance from center and radius of circle is 13cm.

The radius of a circle with centere P is 25 cm . The length of a chord of the same circle is 48 cm . Find the distance of the chord from the centre P of the circle.

PS is the chord of the circle with centre O. A perpendicular is drawn from centre O of the circle to chord PS at M. If bar(PS) =30 cm and bar(OM) =8 cm , then find the radius of the circle.
