Answer:[tex]34,650\ in^3[/tex]
Step-by-step explanation:
Given
The height of the aquarium is [tex]h=25\ inches[/tex]
The radius of the aquarium is [tex]r=21\ inches[/tex]
Assuming aquarium to be in the shape of a cylinder
So, its volume is [tex]V=\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 21^2\times 25\\\Rightarrow V=34,650\ in^3[/tex]
Thus the volume of the aquarium is [tex]34,650\ in^3[/tex].
