Answer:
64π m³
Step-by-step explanation:
The general formula for the volume of a cylinder: 
V = πr²h, where 'r' is the radius and 'h' is the height
In the given problem, the radius is equal to 4 m and the height is equal to 4 m.  Plugging these values into the equation: 
V = π4²(4) = π16*4 = 64π m³
 
        
             
        
        
        
Answer:
Mary's mistake was that she didn't take into account of the power that 10 is raised to; since 2.01 is multiplied by 10 to the 6, it makes 2.01 bigger. You can also expand the number to check:
2 010 000 vs. 4800
 
        
             
        
        
        
2+1.25f=10-2.75f      Add the variables
2+4f=10                   isolate the variable
4f=8                          
f=2
