Final answer:
The equation |r| = 5 represents a sphere with a radius of 5 units.
Step-by-step explanation:
The equation |r| = 5 represents a sphere with a radius of 5 units in three-dimensional space. The absolute value bars denote the magnitude of the vector r, which is always positive. Therefore, all points on the sphere are equidistant from the origin.
