.
A HOLLOW metal cylinder is 3cm long 4 cm in external diameters
and metal is 5mm thick .the dencity of the metals is 2.8 g/cm3. find the mass of the cylinder
~~~~~~~~~~~~~~~

First, calculate the volume of the metal.


For it, from the volume of the bigger cylinder, subtract the volume of the hole, which is smaller cylinder.


By knowing the metal volume, multiply it by the density to get the mass of the hollow cylinder.

All needed instructions are given.
