The length of tangent PQ, from an external point Q, is 24 cm. If the distance of the point Q from the center is 25 cm, then the diameter of the circle is

In the given figure, RQ is a tangent to the circle with center O. If SQ = 6 cm and QR = 4 cm, then OR is equal to

In the figure, PT is tangent to the circle with center O such that OP is 4 cm and ∠OPT=30^o length of the tangent is given by :

If PT is a tangent to the circle with center O, then x + y is equal to

A tangent PQ at a point P o a circle of radius 5 cm meets a line through the center O at point Q, so that OQ = 12 cm. find the length PQ.

If the angle between two radii of a circle is 130^o, the angle between tangents at ends of radii is :

In the given figure, the measure of ∠OQPis

In the adjoining figure, the measure Of PR is

PT is a tangent of the circle with center O and ∠TPO = 25^∘, then the measure of x is

In the figure given alongside the length of PR is
