Question

Answer 1

Step-by-step explanation:

hii mate

Let A=(5,6) and C=(2,0) (center of the given circle). Then the radius of the smaller circle touching the given circle and passing through A will be (AC−2)/2 Likewise the radius of the bigger circle will be (AC+2)/2. Thus

r1r2=(AC2−4)/4=[(5−2)2+(6−0)2]−44=41/4.
