Answer 2

The equation you've written is x² + y² + z² = 49. This equation represents a sphere in three-dimensional space.

In this equation:

• x represents the x-coordinate of a point in three-dimensional space.
• y represents the y-coordinate of a point in three-dimensional space.
• z represents the z-coordinate of a point in three-dimensional space.

The equation x² + y² + z² = 49 describes all the points (x, y, z) that are at a distance of 7 units from the origin (0, 0, 0). This is because the square of the radius of the sphere is 49, so the radius itself is 7.

In geometric terms, this equation represents a sphere with a center at the origin (0, 0, 0) and a radius of 7 units. The points (x, y, z) that satisfy this equation lie on the surface of this sphere.
