Hint:

The radius of the sphere is determined after converting the general equation into the standard form by completing the square.

Answer 1

The Correct Option is A

The general equation of a sphere can be written in the form: $$(x - h)^2 + (y - k)^2 + (z - l)^2 = r^2$$ where $h$, $k$, and $l$ are the coordinates of the center, and $r$ is the radius. The radius is obtained by completing the square for each term.
