## Homework Statement

I was asked to show the circle $x^2$ + $y^2$ +6$x$ -10$y$ +9=0 lies entirely inside circle $x^2$ + $y^2$ +4$x$ -6$y$-48=0...

For circle $x^2$ + $y^2$ +6$x$ -10$y$ +9=0

I managed to get the centre = (3,5) r=5

For circle $x^2$ + $y^2$ +4$x$ -6$y$-48=0

i gt centre = (2,3) r= sqrt 61How to proceed from here ??
