The correct statement about the diameter of a sphere is:
The diameter of a sphere passes through the center of the circle.
To elaborate:
- The diameter is a chord, specifically the longest chord of the sphere.
- The diameter is not 2.5 times the length of the radius; it is actually 2 times the length of the radius (Diameter = 2 × Radius).
- The diameter is not the shortest length on a sphere; there are other shorter chords.
- The diameter does indeed pass through the center of the sphere.
