Andy has two similar conical hats, Hat A and Hat B. The diameter of Hat A is 18 inches, and the diameter of Hat B is 9 inches.

What is the ratio of the volume of Hat A to the volume of Hat B?

2:1
16:1
4:1
8:1

is it 4:1? or 8:1? or something else?

Respuesta :

The answer is 2:1 because at first your ratio would be 18:9 but if you divide that by 9 (for simplifying purposes) than its 2:1
