A meter rod may not fit cross-wise inside a breaker (whatever that is).
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.

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 vernier caliper or a micrometer can be used to measure the internal diameter of a beaker. These tools provide accurate measurements of dimensions, including internal diameters, with precision.
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
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.
A micrometer or caliper can be used to measure the diameter of a test tube accurately. These tools provide precise measurements by directly reading the diameter of the test tube in millimeters.
The theory for the internal diameter of a drinking straw is based on the flow rate of the liquid being consumed and the desired drinking experience. A larger internal diameter allows for faster flow rates, while a smaller diameter creates more resistance and controls the flow. Factors such as the liquid's viscosity, surface tension, and the user's preference also play a role in determining the internal diameter of a drinking straw.
To measure the diameter of a capillary tube using a traveling microscope and vernier caliper, place the capillary tube on a flat surface. View the capillary tube through the traveling microscope to measure the external diameter. Then, use the vernier caliper to measure the internal diameter by gently inserting the capillary tube between the jaws of the caliper to get an accurate measurement. Subsequently, calculate the average diameter using the two measurements.
