Which of the following is true about the diameter of a sphere? (1 point)

Question

The diameter of a sphere passes through the center of the circle.
The diameter is 2.5 times the length of the radius.
The diameter is the shortest length on a sphere.
• The diameter is not a chord.

Answer 1

The following statement about the diameter of a sphere is true:

The diameter of a sphere passes through the center of the circle.

Let's clarify the other statements:

1. "The diameter is 2.5 times the length of the radius" - This is incorrect. The diameter is actually 2 times the radius (D = 2r).

2. "The diameter is the shortest length on a sphere" - This is also incorrect. The diameter is the longest chord of a sphere, not the shortest length.

3. "The diameter is not a chord" - This is incorrect as well. The diameter is a specific type of chord that passes through the center of the sphere (or circle).

So, the first statement is the only true one.
