What is the similarity ratio of the smaller to larger similar cones?

larger one v=1024 pi m^3

smaller one v=250 pi m^3

V=1024 pi m^3 and v=250 pi m^3

the similarity ratio of the smaller to larger similar cones is

k = V/v=1024 pi m^3/250 pi m^3 = 4.096

the great cone is 4.096 times of the small cone (in volume)
