How much water can this container hold?Express your answer in terms of pie.

Answer: [tex]972\pi\ in.^3[/tex]
Step-by-step explanation:
From the given picture, it can be seen that the diameter of the sphere = 18 inches
Then, the radius of the sphere =[tex]\dfrac{18}{2}=9\ in.[/tex]
The volume of the sphere is given by :-
[tex]\text{Volume}=\dfrac{4}{3}\pi r^3\\\\\Rightarrow\text{Volume}=\dfrac{4}{3}\pi (9)^3\\\\\Rightarrow\text{Volume}=972\pi\ in.^3[/tex]
