Answer:
![508.9\ in^{3}](https://tex.z-dn.net/?f=508.9%5C%20in%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh)
In this problem we have
![r=18/2=9\ in](https://tex.z-dn.net/?f=r%3D18%2F2%3D9%5C%20in)
![h=2\ in](https://tex.z-dn.net/?f=h%3D2%5C%20in)
substitutes
![V=\pi (9^{2})(2)=162\pi\ in^{3}](https://tex.z-dn.net/?f=V%3D%5Cpi%20%289%5E%7B2%7D%29%282%29%3D162%5Cpi%5C%20in%5E%7B3%7D)
Assume ![\pi =3.1416](https://tex.z-dn.net/?f=%5Cpi%20%3D3.1416)
![V=162\pi\ in^{3}=162(3.1416)=508.9\ in^{3}](https://tex.z-dn.net/?f=V%3D162%5Cpi%5C%20in%5E%7B3%7D%3D162%283.1416%29%3D508.9%5C%20in%5E%7B3%7D)
Answer:
<u>37.68</u>
Step-by-step explanation:
Circumference = Diameter x pi
Diameter = 12 feet
12 x 3.14 = 37.68
The circumference of the pool is 37.68 feet.
