The figure appears to be a cylinder with the following dimensions:
Radius = 8 km
Height = 4 km
To be able to determine its volume, we will be using the following formula:
![\text{ Volume = }\pi r^2h](https://img.qammunity.org/2023/formulas/mathematics/college/sd2nmedmn3p3y9yvzun69exhshpn2emxqa.png)
Where,
r = radius
h = height
We get,
![\text{ Volume = }\pi r^2h](https://img.qammunity.org/2023/formulas/mathematics/college/sd2nmedmn3p3y9yvzun69exhshpn2emxqa.png)
![\text{ = (3.14)(8)}^2(4)](https://img.qammunity.org/2023/formulas/mathematics/college/st3edantf3382d1idyhlufmguu0kszg8vw.png)
![\text{ = (3.14)(64)(4)}](https://img.qammunity.org/2023/formulas/mathematics/college/j3ij3lldicvhb7zdg52yhq0ooi5c97p3sy.png)
![Volume=803.84km^3](https://img.qammunity.org/2023/formulas/mathematics/college/7yxmayqmcvl7f73zlfidwb9z8q6op711pl.png)
Therefore, the volume of the cylinder is 803.84 cubic kilometers.
