In the given figure, AB is the diameter of a circle and P is a point on AB extended.
A tangent from P touches the circle at Q. If PQ = 4 cm and PA = 8 cm ,
then the radius of the circle is ____ cm.
A cylinder whose height is two thirds of its diameter has the same volume as a sphere of radius 4 cm. The radius of the base of the cylinder will be
