Option B : The area of the circular base multiplied by the height of the cylinder
        
             
        
        
        
The absolute value is how far away a number is from the number line, so it is always positive. If Carlos finds the opposite of the absolute value, that means he found the negative version. So Jason's final value will be greater.
