True. The radius is half the diameter.
True
True !! it is also a straight line from one side of the circle, through the middle point to the other side of the circle. Any other straight line inside a circle, that does NOT touch the centre is a chord.
The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
Yes, it is true. Any circles with the same radius will have the same circumference as well.
True. The diameter of a circle is always twice the length of the radius. In other words, if we denote the radius of a circle as "r," then the diameter can be expressed as "2r." This relationship holds true for all circles, regardless of their size.
True. The radius is half the diameter.
A true and useful definition of "radius" is that it's 1/2 of the diameter.
It varies on how large the diameter and radius is. True, but with the radius you know to double it and you have the diameter. If you muliply Pi (3.14....) times the diameter, you get the circumference. So radius = circumference divided by Pi, with that answer (which is "diameter")then divided by two.
True
That it is half the diameter of a circle
It is not true
True !! it is also a straight line from one side of the circle, through the middle point to the other side of the circle. Any other straight line inside a circle, that does NOT touch the centre is a chord.

The length of a sphere is its diameter
true
Because it was not
