*6. In the figure, the larger circle, centre O, intersects the smaller circle at P and R. Q is another point on the smaller circle such that QRS is the tangent to the larger circle at R. (a) Show that QPT is also the tangent to the larger circle at P. (b) If PQ = 3 cm and the radius of the smaller circle is 2.5 cm, find the radius of the larger circle.
