By definition, the volume of a cylinder is given by:
  
 Where,
 r: cylinder radius
 h: cylinder height
 Therefore, the total capacity of the container is:
  
 Rewriting we have:
  
 Then, the amount of total dust is given by:
 
 Where,
 V: volume of the container
 Substituting values:
 
 Rewriting:
  
 Answer:
 The total capacity of the container in terms of π is:
  
 The volume of the powder in terms of π is:
 
 
        
             
        
        
        
The first step to factorize is to find the common terms. In this 5a is common throughout. By taking it out we get the expression: 
5a (3 a^2 -b)
