Answer:
The volume of the sphere is ![V=18\pi\ ft^{3}](https://tex.z-dn.net/?f=V%3D18%5Cpi%5C%20ft%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of cylinder is equal to
![V=\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh)
we have
![V=27\pi\ ft^{3}](https://tex.z-dn.net/?f=V%3D27%5Cpi%5C%20ft%5E%7B3%7D)
substitute
![27\pi=\pi r^{2}h](https://tex.z-dn.net/?f=27%5Cpi%3D%5Cpi%20r%5E%7B2%7Dh)
simplify
Remember that
A sphere and a cylinder have the same radius and height
so
The height of cylinder is equal to the diameter of sphere
h=2r
substitute
-----> equation A
The volume of the sphere is equal to
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
substitute equation A in the formula of the volume of sphere
![V=\frac{4}{3}\pi (13.5)](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%2813.5%29)
![V=18\pi\ ft^{3}](https://tex.z-dn.net/?f=V%3D18%5Cpi%5C%20ft%5E%7B3%7D)
I think it’s a because the lines kinda looks perfect but I might be wrong.
