Answer:

Approximately 377 cubic inches of water.

Step-by-step explanation:

We know that Mary wants to fill in a cylinder vase and she was told that the vase should be filled 3/4 for the flowers to last the longest. We are to find how much water should she pour into the vase.

So first, we will find the height of the water:

$=\frac{3}{4} *10=7.5$ inches

Then, find the volume of the water of this height:

$Volume = \pi *4^2*7.5 = 376.9$

Therefore, Marry should pour approximately 377 cubic inches of water.
