Best ResponseYou've already chosen the best response.1Now you can say that all radii of a circle are equal so all radii of circle C = 4 and all radii of circle E = 3 so the ratio of all radii of Circle C to all radii of Circle E= 4:3 so the circles are similar and by extension all circles are similar.
