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

im am fairly sure that it is not 4: 1, but that's all i know.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
