a meniscus
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.
A graduated cylinder is called such because it is more than just a cylinder. It is a cylinder used to measure liquid volume precisely. It is technically "smarter" than a cylinder hence it is "graduated".
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.In other words, holding the graduated cylinder at eye level, the bottom of the curved surface of the liquid (called the meniscus) is where you read off the mark on the graduated cylinder to determine the volume properly.

A graduated cylinder is a glass or plastic device used in laboratory to measure volume of liquids.
When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the ... For mercury, take the measurement from the top of the meniscus. ...
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."

The meniscus. Make sure to always measure at that point. If your graduated cylinder/pipet/etc has the meniscus at 10 mL then the glassware has 10 mL in it.
The slight dip in a graduated cylinder is called a meniscus.
