formula for volume of cylinder Pi x r x rxh solution therefore is
(3.14)(0.25 x0.25) ( 1.5)= 9.8125
remember that diameter is given so get its half
to get the weight, check out its density.... then compute using
D= Mass / volume

To start with, the volume of a cylinder with those dimensions is much less that 3 cubic metres.
Assuming you do actually know the volume, the weight will depend on what you are putting into the volume. Water weighs approximately 1 kilogram per litre. Air (at standard temperature and pressure) is much lighter.

Your cylinder has a volume of 1.178097 m^3, not 3 m^3
to calculate the weight in either case you must have the density as well.

You need to know the density of the liquid you are storing there. Then you multiply the density by the volume (make sure you use the same units of measure!)
