Answer:
904.78
Step-by-step explanation:
we have the radius, which is 6.
were trying to find the volume.
the foemula for the v of a sphere is 4/3(pi)r^3
so, multiply 4/3 times pi and we get 4.18879.
find 6^3, which is 216. multiply tyese two values, and we get 904.77864.
so, the volume of this sphere is around 904.78
