A line through the centre `O` of a circle of radius 7 cm cuts the tangent, at a point `P` on the circle, at `Q` such that `P Q=24 c m` . Find `O Q` .

O is the centre of a circle of radius 8cm. The tangent at a point A on the circle cuts a line through O at B such that AB=15cm. Find OB.

A is a point at a distance 13 cm from the centre O of a circle of radius 5 cm. AP and AQ are the tangents to the circle at P and Q. If a tangent BC is drawn at a point R lying on the minor arc PQ to intersect AP at Band AQ at C, find the perimeter of the Delta ABC

From a point P which is at a distance of 10 cm from the centre O of a circle of radius 6 cm, a pair of tangents PQ and PR to the circle at point Q and P respectively, are drawn. Then the area of the quadrilateral PQOR is equal to
