I need help with this question

Answer:
Amount of Water needed to be filled is 150.79 cubic inches
Step-by-step explanation:
The volume of the flower vessel which is in cylinder form is given as
[tex]V = \pi r^2h[/tex]
Where r is the radius and h is the height
r = 3 and h = 8
Hence
[tex]V = \pi \times 3^2 \times 8[/tex]
[tex]V = 3.14 \times 9 \times 8[/tex]
V= 226.19
Hence Volume of the vessel is 226.19 cubic inches
She was told that she is supposed to fill the vessel only [tex]\frac{2}{3}[/tex] of the total volume
Hence the amount of water to be filled will be
[tex]\frac{2}{3} \times 226.19[/tex]
150.79 cubic inches
