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:
[tex]=\frac{3}{4} *10=7.5[/tex] inches
Then, find the volume of the water of this height:
[tex]Volume = \pi *4^2*7.5 = 376.9[/tex]
Therefore, Marry should pour approximately 377 cubic inches of water.
