PLEASE HELP If two cones are similar with cone A having a base area of 9r cm’ and cone B has a base
area of 251 cm?, what is the similarity ratio?
a) 9:25
b) 27:125
c) 4:6
d) 3:5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

1,8,15,22,29,36,43,50
