Answer:
![39,865.1m^3](https://tex.z-dn.net/?f=39%2C865.1m%5E3)
Step-by-step explanation:
a hemisphere is half a sphere.
And if the formula for the volume of a sphere is:
![V=\frac{4\pi r^3}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%5Cpi%20r%5E3%7D%7B3%7D)
we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.
Since the radius is:
![r=26.7m](https://tex.z-dn.net/?f=r%3D26.7m)
substituting this into the formula for volume:
![V=\frac{4\pi (26.7m)^3}{3} \\\\V=\frac{4(3.1416)(19,034.163m^3)}{3} \\\\V=79,730.12m^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%5Cpi%20%2826.7m%29%5E3%7D%7B3%7D%20%5C%5C%5C%5CV%3D%5Cfrac%7B4%283.1416%29%2819%2C034.163m%5E3%29%7D%7B3%7D%20%5C%5C%5C%5CV%3D79%2C730.12m%5E3)
this is the volume of the total sphere, thus the volume of a hemisphere is:
![\frac{V}{2}=\frac{79,730.12m^3}{2}\\ =39,865.06m^3](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B2%7D%3D%5Cfrac%7B79%2C730.12m%5E3%7D%7B2%7D%5C%5C%20%20%3D39%2C865.06m%5E3)
rounding to the nearest tenth:
![39,865.1m^3](https://tex.z-dn.net/?f=39%2C865.1m%5E3)
