Answer:
![890.75m^3](https://tex.z-dn.net/?f=890.75m%5E3)
Step-by-step explanation:
Step one:
given data
heigth/depth = 3.5m
radius= 9m
Step two:
The shape is that of a cylinder
Hence the volume of the pool is
![V= \pi r^2h](https://tex.z-dn.net/?f=V%3D%20%5Cpi%20r%5E2h)
substitute
![V= 3.142*9^2*3.5\\\\V=890.75 m^3](https://tex.z-dn.net/?f=V%3D%203.142%2A9%5E2%2A3.5%5C%5C%5C%5CV%3D890.75%20m%5E3)
