1)In the given figure, PA is a common tangent and QB and PC are the tangents from Q and P to the
smaller and larger circle respectively.
if QB=5cm and PC=9 then evaluate the length of PQ
2)Tangent segments PS and PT are drawn to a circle with centre O such as <SPT=120. Prove that OP=2PS
3)The length of tangent PQ, from an external point P is 24 cm. If the distance of the point P from the centre is 25 cm, then find the diameter of the circle.
