Answer:
The region represented by the equation is a full sphere of radius √3 centered in the origin of coordinates.
Step-by-step explanation:
<em>In a plane xy, the equation that represents a circle with center in the origin, of radius r is</em>

<em>in R³, or a space xyz, we can represent a sphere with its center in the origin, and of radius r, with the equation</em>

So, in this problem we have that

which means that the sphere has a radius of √3.
<u>Finally, our equation is an inequality</u>, and the sphere is equal to, and less than, the calculated radius.
Therefore, the sphere is "full" from the surface to its center.
Solution set is: (
)
Option B is correct
Step-by-step explanation:
We need to find the solution to system of equations

Let:

Putting value of y from eq(2) into eq(1)

So, value of x=7
Putting value of x into equation 1 to find the value of y:

So, value of y = 
Solution set is: (
