you have to distribute the + into -5 which will still be -5r and you keep the 10
        
                    
             
        
        
        
-5x+4-x-1
combine the like terms first
-5x-x+4-1
-5x-x=-6x
+4-1=3
answer:
-6x+3 or 3-6x

Volume of cylinder = pi r^2 h  
diameter = S  so the radius = 0.5S  and the height of cylinder = S 
so Volume of this cylinder = pi (0.5S)^2 * S
                                           
                                          =  0.25 pi S^3
