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.
