i have done a method and i cant complete it
let P and Q be two pts on the circle x2+y2=4 and (x-3)+(y-3)2=9 respectively and the diameter of the smallest circle shud be the maximum distance between P and Q
there P(h,k) and Q(p,q)
(h-p)2+(k-q)2=l2
and i dont know how to proceed after this and i have only two eqns but 4 knowns i cant find any other eqns can anyone find a ways to this method please post
and if u got any other method please post
