None of the answers are correct.
The volume of a sphere is
4 π r^3 / 3
= 4 π 7^3 / 3
= 4 * 343 * π / 3
= 457.33 * π
= 1436.76
The answer you quote in the update has missed out the multiplication by Pi.
1436.76 does not match any of the answers in your question.

V = (4/3)(π)(r^3)
V = (4/3)(π)(7^3)
V = (4/3)(π)(343)
V= (1372 / 3)π cm^3
Final Answer: C
