Let's examine each statement to determine which is true about the diameter of a sphere:
1. "the diameter of a sphere passes through the center of the circle":
- This is partially true but slightly misstated, as the correct term should be "sphere" rather than "circle." A diameter of a sphere is indeed a line segment that passes through the center of the sphere and has its endpoints on the sphere's surface.
2. "the diameter is not a chord":
- This statement is false. A diameter is a special case of a chord. In a circle or sphere, a chord is a line segment with both endpoints on the sphere's surface. The diameter is the longest possible chord in a sphere, passing through the center of the sphere.
3. "the diameter is 2.5 times the length of the radius":
- This statement is false. The diameter of a sphere is exactly twice the length of the radius (D = 2r).
4. "the diameter is the shortest length on a sphere":
- This statement is false. The diameter is the longest straight line you can draw within a sphere, not the shortest. The shortest length between two points on a sphere's surface is not a straight line through the interior of the sphere, but rather an arc along the surface, which is part of a great circle.
The correct statement about the diameter of a sphere is therefore the first one, with the term "circle" replaced with "sphere." To summarize, the diameter of a sphere passes through the center of the sphere, is a special case of a chord, is twice the length of the radius, and is the longest straight line segment that fits entirely inside the sphere.
Which of the following is true about the Diameter of a sphere
the diameter of a sphere passes through the center of the circle
the diameter is not a chord
the diameter is 2.5 times the length of the radius
the diameter is the shortest length on a sphere

Just choose one
Apologies for any confusion. If I have to choose one statement that is true about the diameter of a sphere, it would be:
"The diameter of a sphere passes through the center of the sphere."
(Note: I've corrected "circle" to "sphere" to make the statement accurate.)
"The diameter of a sphere passes through the center of the sphere."
(Note: I've corrected "circle" to "sphere" to make the statement accurate.)
