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.
A meter rod may not fit cross-wise inside a breaker (whatever that is).
The drum should measure 23 inches diameter 36 inches height These are all external measurements.
Internal diameter.
The radius of a circle is half the diameter.
Calipers are used to measure the dimension of anarticle. In measuring a section of pipe you would use an inside caliper to give the internal diameter, and an outside caliper to give the external diameter. The difference being the thickness of the pipe wall.
A meter rod may not fit cross-wise inside a breaker (whatever that is).
External diameter, internal diameter, and tooth count.
A set of calipers.
Measure external diameter. (A) Measure internal diameter. (B) Subtract B from A
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
