Answer
A solid sphere centered at the origin with radius $\sqrt 3$.
Work Step by Step
The given inequality has the form of a sphere centered at the origin with radius less than or equal to $\sqrt 3$. This inequality therefore represents all the spheres with radii less than or equal to $\sqrt 3$ and center at (0, 0, 0). Putting all these together, we get a solid sphere with radius $\sqrt 3$ and center (0, 0, 0).
