Answer:
 r² x h
 r² x h 
Step-by-step explanation:
A can is cylindrical in nature. Using the formula of the volume of the can, we can find this unknown volume. 
The volume of cylinder is given as: 
 Volume of a cylinder = Area x height 
 Volume of a cylinder = 
 r² x h
 r² x h 
Therefore density of the can;
 
 Density =
