Read the level of the liquid at the mark on the cylinder.
I think you are talking about a graduated cylinder. When measuring liquids in a grad. cylinder you should read at the bottom of the miniscus ( the curved surface of the water or other liquid).
Of a solid, measuring the quantity of fluid displaced by the object should suffice. Of a liquid, measuring its volume with a measuring cylinder or similar. Of a gas, measuring its mass or volume under conditions of standardized temperature and pressure
The curve on a graduated cylinder is called a meniscus. It occurs due to surface tension between the liquid and the container, causing the liquid to curve at the edges. When measuring volume in a graduated cylinder, the bottom of the meniscus should be used for accurate readings.

A 10 mL graduated cylinder should do the job nicely
with measuring tools
The upper surface of the liquid in a graduated cylinder is called the meniscus. It appears curved due to surface tension, and the measurement should be read at the bottom of the meniscus for an accurate volume reading.
You should always measure the volume of liquid in a graduated cylinder at the bottom of the meniscus, where the curve of the liquid meets the cylinder's surface. This ensures an accurate reading of the volume contained in the cylinder.
A graduated cylinder would work.

To get an accurate liquid volume measurement, ensure the measuring container is on a level surface, read the measurement at eye level to avoid parallax errors, and use the appropriate measuring tools calibrated to the desired units.
