Volume of cylinder = 2pierh + 2pier^2
= 2*3.14*4.5*13 + 2*3.24*4.5^2
= 494.8

Answer: 827 cubic feet

Step-by-step explanation:

The volume of a cylinder is given by :-

[tex]\text{Volume}=\pi r^2 h[/tex], where r is radius and h is height of the cylinder.

Given : The radius of a cylindrical water tank is 4.5 ft , and its height is 13ft .

Then , the height of the  cylinder will be :-

[tex]\text{Volume}=(3.14)(4.5)^2(13)\\\\\Rightarrow\ \text{Volume}=826.605\approx827\text{cubic feet}[/tex]

Hence, the volume of the tank = 827 cubic feet
