Volume of cylinder: base squared times length
v=l*b
Volume of a cylinder in cubic units = piradius2height
The diameter, alone, is not enough to find the volume of a cylinder. You need the height as well. > Where pi = 3.1416, and d = cylinder diameter cylinder volume = pi * (d/2)2 * length of cylinder

To calculate the volume of a cylinder one must multiply the area of the circle by the depth of the cylinder. The volume of the cylinder described is 98.172 cubic feet.

Volume of a cylinder = pi*radius2*height in cubic units
Drop the object into a graduated cylinder 50 mL half full of water and find the difference in volume. If it is too big for a measuring cylinder then make a small hole in the side of a plastic container, fill with water to this hole, drop the object in and collect the run off. Measure the volume of the run off.

Density = Mass/Volume, correct. However, with a cylinder, you have to find the volume. In order to find the volume of a cylinder use the equation PiR2 * H where "R" is the radius (Diameter/2) squared.
Volume of a cylinder = pi*(radius)2*(height) where pi = 22/7
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.
