Hello!
The formula for the volume of a sphere is [tex] \frac{4}{3} \pi r [/tex]³.
Let's plug in our radius.
[tex] \frac{4}{3} \pi (1,000) [/tex]
As we are not looking for an exact answer,we can look for an answer in terms of pi. Maybe we could multiply our fraction by 1,000.
[tex] \frac{4000}{3} \pi [/tex]
Therefore, our answer is D.
I hope this helps!
