In the given figure, O is the centre of a circle of radius 13 cm and AB is a chord perpendicular to OD. If CD = 8 cm, then what is the length (in cm) of AB?

O is the circum centre of the triangle ABC with circumradius 13 cm. Let BC = 24 cm and OD is perpendicular to BC. Then the length of OD is

In the figure PQ is a diameter of a circle with centre O.QR is a tangent to the circle equal to OQ.OT is perpendicular to PR.QT is produced to cut the circle at S Prove that SP=ST

If PQ be a diamter of a circle with centre at O and if PR= RQ, then the value of angle RPQ is

If Figure - 4, AB and CD are two diameter of a circle (with centre O) perpendicular to each other and OD is the diameter of the smaller circle. IF OA = 7 cm, then find the area of the shaded region.
