This is one of those questions where, if you know the formula, it's easy,
and of you don't know the formula, there's no way.
In fact, the whole purpose of the question is to help you remember the formula.
The volume of a cylinder is
                           (pi) x (the radius)² x (the height).
For this particular cylinder, that's 
                            (pi) x (3)² x (10) = 
                           (pi) x (9) x (10)  =  90 pi cubic units.
If you use (3.14) for (pi), then that's  <em>282.6 cubic units</em>.
  
        
             
        
        
        
So you have 20% of blue and 50% of black. 
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black
