well what is your question and i could help.
These glasswares can be ranked from the least accurate (1) to the most accurate (3) as follows;
Beaker - 1
Graduated cylinder - 2
Volumetric pipette - 3
The beakers are considered to be the least accurate since they are in graduations of 25 or 50 ml. They are also not calibrated during manufacturing.
Graduated cylinders are more precise than beakers since they have permanently marked incremental graduations incorporated in the cylinder hence making them more accurate at reading the volumes of the inside liquids.
Volumetric pipettes are the most accurate as compared to the other two given glassware as they allow the measurement to four significant figures and have an error of a few hundredths of a milliliter.
