Question

Two spheres have a scale factor of 3:2 what is the ratio of the diameters of the spheres? 

9:4
13:12
27:8
3:2

Answer 1

I worked it out and got 27:8. Sorry if I’m wrong, that’s the answer I got while working it out.

Answer 2

9514 1404 393

Answer:

(d) 3:2

Explanation:

Usually, when we say two objects are related by a scale factor, we are talking about the linear dimensions of the objects. Here, we're concerned with the ratio of diameters. The diameter is a linear dimension of the sphere, so the ratio of diameters is the same as the scale factor:

3:2
