Which of the following is true about the diameter of a sphere
1.The diameter of a sphere passes through the center of the circle.
2.The diameter is the shortest length on a sphere.
3.The diameter is 2.5 times the length of the radius.
4.The diameter is not a chord.
1. The diameter of a sphere passes through the center of the circle - This statement is true. The diameter of a sphere is a straight line segment that passes through the center of the sphere and is the longest chord possible.
2. The diameter is the shortest length on a sphere - This statement is false. The diameter is actually the longest length on a sphere. Any other chord of the sphere will be shorter than the diameter.
3. The diameter is 2.5 times the length of the radius - This statement cannot be determined solely based on the information provided. The relationship between the diameter and radius of a sphere is that the diameter is always equal to twice the length of the radius, so this statement would be true if "2.5" was replaced with "2."
4. The diameter is not a chord - This statement is false. The diameter of a sphere is a specific type of chord that has the special property of passing through the center of the sphere.
