The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
A standard CD:- 15mm Internal diameter, 120mm external diameter, 1.1 mm thick A mini CD:- 15mm Internal diameter, 80mm external diameter, 1.1 mm thick
Subtract 50cm from external diameter.
If it is a diameter then you must be in a cylinder or domed room. To get the thickness take the external and subtract the internal then divide the result in half.
To get the accuracy or to get the relative deviation.
Assuming it is a rod, the difficulty lies in that it can't measure the diameter of the beaker. Unless you were to attempt to find out the Radius/Diameter, then work out the circumference from that.

External diameter minus internal diameter will get you the difference and then you have to divide by two to get the wall thickness. (as the difference in diameter accounts for both sides of the cylinder)
External diameter, internal diameter, and tooth count.

25.5 mm is.
It is not possible to answer this without more information. However to find the thickness measure the external diameter, measure the internal diameter subtract the internal from the external and that will give you the thickness of the pipe
Measure external diameter. (A) Measure internal diameter. (B) Subtract B from A
A caliper can be used to measure the internal and external diameter of a tube with about a 5cm bore. Make sure to use the appropriate jaws of the caliper for accurate measurements. Alternatively, a micrometer can also be used for precise measurements of the tube's diameter.
