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.

Actually, answer 1 is for the volume, not the surface area. Aside from that, there are lots of ways to bore a hole in a cylinder. If it goes from one base (a flat face) to the other (or part of the way) parallel to the axis, answer 1 is correct (for the volume). If it is not parallel to the axis, or if it is bored from the curved surface of the cylinder, it is much more complicated. Assuming, as in answer 1, that the hole goes all the way from one base to the other parallel to the axis, to get the surface area you would add the surface area of the outer cylinder to that of the hole (just the curved surface portion), and then subtract the areas of the circular holes in the two bases, each of which is pi x the radius of the hole squared. I'm assuming you know how to calculate the surface area of a cylinder. This is the area of the curved surface, which is 2 x pi x the radius x the height, plus 2 x the area of each base, which is pi x the radius squared. ========================================================== Use the formula:- Volume of a cylinder = Pi X Radius squared X Length , to find the volume of a solid cylinder. Repeat the same calculation with the same formula, to find the Volume of the cylinder of fresh air within the cylinder . Subtract the fresh air Volume from the Solid Cylinder Volume. That will be your answer . Think about your problem, then it is dead easy.
First we must find the radius: Curved surface area of the cylinder excluding the two end pieces = 88 cm2 2*pi*radius*14 = 88 Divide both sides by 2*pi*14 radius = 1.000402499 cm Volume = pi*1.0004024992*14 Volume = 44.01770994 cubic cm

if u r talking about its volume then its formula is 22/7 . square of radius . height and its curved surface area is 22/7 r l

To accurately measure the volume of a liquid in a graduated cylinder, you must read the measurement at the bottom of the meniscus, which is the curved surface of the liquid caused by surface tension.
To find the volume of a curved cylinder, you would use the formula: V = πr^2h, where r is the radius of the curved surface and h is the height of the cylinder. Calculate the values for r and h from the given measurements and plug them into the formula to find the volume.

To read the volume of water in a graduated cylinder, make sure your eye is level with the meniscus (the curved surface of the water). Read the volume at the bottom of the meniscus to get an accurate measurement. Ensure the graduated cylinder is on a flat surface to prevent parallax errors.
Volume readings are made at the bottom of a curved surface called the meniscus. This is due to surface tension pulling the liquid up the walls of the container, creating a curve at the top of the liquid. When taking volume measurements, it is important to read the volume at the bottom of this curved surface for accuracy.
First we must find the radius: Curved surface area of the cylinder excluding the two end pieces = 88 cm2 2*pi*radius*14 = 88 Divide both sides by 2*pi*14 radius = 1.000402499 cm Volume = pi*1.0004024992*14 Volume = 44.01770994 cubic cm
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."
