incomplete question but you can solve it by
c1c2=r1+r2
c1c2=r1+r2

Dear deepak ,
My qustions is what exactly you need to prove ?The definition and equation of two circles is ok but what the student wants to prove that is not clear.
Please specify that. I will answer any thing you want to ask but specify clearly?
