The volume of a sphere is 
So, if the small sphere has radius
and the largest sphere has radius
, their volumes are

So, their ratio is

Answer: x = 12 and y = -8
Explanation:
x + y = 4
4x + 3y = 24
———————
-3(x + y = 4)
4x + 3y = 24
———————-
-3x - 3y = -12
4x + 3y = 24
———————
x = 12
If x = 12
x + y = 4
12 + y = 4
y = -8
3x + y = 3
x + y = 2
x = 1/2 and y = 3/2
