Question

(Geometry A) Which of the following could represent the scale factor of the larger figure to the smaller figure?

Answer 1

3:2 and 21:14

Explanation:

Answer 2

Option C. 3 : 2 is the correct option.

Explanation:

In this question the given parameters of the larger figure are r = 18 m amd h = 30 m. and for the smaller one r = 12 m and h = 20 m.

Now we will find the ratio of both larger : smaller one in terms of their radii and height.

Ratio of radii = 18/12 = 3/2

Or r : r' = 3 : 2

Ratio of heights = 30/20 =

Or h : h' = 3 : 2

Therefore only one answer is valid that is 3 : 2.
