ANSWER
The volume of the sphere is
[tex]V= \frac{4}{3} \pi \: {(6)}^{3} [/tex]
EXPLANATION
The volume of a sphere is calculated using the formula;
[tex]V= \frac{4}{3} \pi \: {r}^{3} [/tex]
The given sphere has radius 6 units.
We substitute r=6 into the given formula to obtain;
[tex]V= \frac{4}{3} \pi \: {(6)}^{3} [/tex]
Based on the options provided, we do not have to simplify further.
The second choice is correct.
