C2 center at (2,8) with radius 2 & D2 center (-2,4) with radius 1

Question

Show that two circles are similar by stating the necessary  transformations from C to D draw coordinate plane on graph if necessary 

Answer 1

(x-2)^2 + (y-8)^2 = 4

shift left 4, shift down 4, compress by 1/2

(x+2)^2+ (y-4)^2 = 1
