Answer:
The volume of this cylinder is 9184.5 cubic feet.
Step-by-step explanation:
The area of a circle is
and the volume of a cylinder with that base is just that area times the height:
![V=\pi r^2\times h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%5Ctimes%20h)
Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:
![r=30\times0.5=15](https://tex.z-dn.net/?f=r%3D30%5Ctimes0.5%3D15)
Next, you can use that radius to calculate the area of the base:
![A=3.14\times15^2\\A=3.14\times225\\A=706.5](https://tex.z-dn.net/?f=A%3D3.14%5Ctimes15%5E2%5C%5CA%3D3.14%5Ctimes225%5C%5CA%3D706.5)
Finally, multiply that by the height to find the volume of the cylinder:
![V=706.5\times13\\V=9184.5](https://tex.z-dn.net/?f=V%3D706.5%5Ctimes13%5C%5CV%3D9184.5)
The volume of this cylinder is 9184.5 cubic feet.
