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.

To measure the internal diameter of a bottle, you can use a caliper or a ruler. Insert the caliper's jaws or the ruler into the opening of the bottle, ensuring it touches the inner walls. Read the measurement at the widest point. For more precise results, consider measuring at multiple points and averaging if the bottle has irregularities.
To measure the internal diameter of a tube, you can use a caliper, such as a digital or vernier caliper, by placing the jaws inside the tube and reading the measurement where they touch the inner walls. Alternatively, you can use a small ruler or measuring tape, but this may be less accurate. Ensure the tube is clean and free of debris for an accurate reading. For precision, take multiple measurements at different points along the diameter to account for any irregularities.

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.

Calipers measure the internal or external dimensions of something.
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.
