plzz frnds help me it's too urgent

Answer 1

Let C1
and C2
be two concentric circles , smaller circle
C1 divides the larger circle C2
into two regions of equal
area , where radius of C1
is 2 units , then length of
tangent from any point 'P' on the circle C2
to circle C1
is 2 units..
Hope this helpful
Mark as brilliant. Pls

Answer 2

Answer:Let the given circles C1 and C2 have centres O1 and O2 and radii r1 and r2 respectively.

Let the variable circle C touching C1 internally, C2 externally have a radius r and centre at O
