Want this question answered?
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.
2*pi*r*h=area of curved surface 377=2*3.1428*r*15 r= 4cm Volume=pi*r*r*h 3.1428*16*15 754.27 cubic cm
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

Surface area = 1866 square units.Volume = 6107 cubic units.

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 volume of this cylinder would be 62.857142857142804 cubic units. The surface area of this cylinder would be 87.96459430051421 square units.
A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
