Ответ:
The volume of the cylinder is equal to: V = πr²h. If you want to find the bigger volume to the smaller volume, all you have to do is divide them. Therefore, the ratio is
Ratio = π(7)²h/π(1)²h
Cancel out like terms: π and h. It leaves us with 7² and 1². So, the final answer would be
Ratio = 49
However, the answer is not given in the choices. Therefore, the heights of the cylinders are not equal. There is no way for us to know the exact ratio without the dimensions of the heights. What we can do here is apply reverse engineering. Let's conform the answer to our solution. Suppose the answer is 112:1.
Ratio: 7²*h₂/1²*h₁ = 112
That means h₂/h₁ = 2.285714286
Suppose the answer is 343:1,
Ratio: 7²*h₂/1²*h₁ = 343
That means h₂/h₁ = 7
So, I think the answer is 343:1, because the ratio's of the heights is an exact whole number. This is logical because the dimensions of the heights are also whole numbers.
