Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio

Answer:
33
Step-by-step explanation:
Let's call their ages m and b.
We have:
m = b + 12
m - 17 = 4(b - 17) → m = 4b - 51
b + 12 = 4b - 51
3b = 63
b = 21
m = 21 + 12 = 33
