In terms of the shape of a measuring cylinder, why is a pipette more accurate? Plz answer asap :)

a measuring cylinder is bigger than a pipette,the surface you'll look at when measuring something is also bigger than the surface in a pipette.so when you soup a liquid in a cylinder it's less accurate because your eyes can't be 100 percent right about the reading and there must be some slight fault in the reading.but even it's a small mistake,say a millimeter,this 1 millimeter holds more liquid than a millimeter holds in a pipette.that's why small is bigger in a cylinder and smaller in a pipette,making it more accurate.

A cylinder is, well, cylindrical and the volume is linearly proportional to the height. If you add 1% more liquid you will get a 1% change in the height of the meniscus.
A pipette has a large bulb to hold the liquid, and a narrow tube with the graduating mark. The volume is not at all linearly proportional to height. If you add 1% more liquid you will get a 100% increase in the height of the meniscus, or whatever the ratio is of the x-section areas of the bulb and the narrow tube.
