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 measuring cylinder
When measuring volume in a graduated cylinder, you should read the level at the bottom of the meniscus, which is the curved surface of the liquid. Make sure your eye is level with the meniscus to avoid parallax error. The measurement should be taken at the lowest point of the curve for an accurate reading.

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.
If using a graduated cylinder, take into consideration the meniscus, which presents itself as a concave depression on the surface of the liquid in a cylindrical vessel or a convex bulge if such a container is filled to the brim. The height of the meniscus should be divided in half. If you don't have a graduated cylinder, utilize the formula pi times radius squared times the height (don't forget to adjust for the meniscus) of the liquid in a cylinder.
