Answer:
13.1mi
Step-by-step explanation:
Length(l) = 4.1mi
Breadth(b) = 2.5 mi
Perimeter of a rectangle = addition of all sides that is = l + l + b + b as a rectangle has 2 opposite equal length and also breadth. 
Therefore perimeter = 4.1 + 4.1 + 2.5 + 2.5
= 8.1 + 5
=13.1 mi

The median is 19.5. 16+23 is 39. 39/2 is 19.5
        
                    
             
        
        
        
Base Surface Area = π×42
= 50.265482457437 inches2
Lateral Surface Area = π×4×√42 + 4.72440944881892
= 77.789838023204 inches2
Total Surface Area = 128.05532048064 inches2
Or in square centimeters:
Base Surface Area = π×10.162
= 324.2927866224 centimeters2
Lateral Surface Area = π×10.16×√10.162 + 122
= 501.8689189905 centimeters2
Total Surface Area = 826.1617056129 centimeters2
        
             
        
        
        
A is the answer because it does not repeat any of the x numbers
        
             
        
        
        
We have to compare diameters and arrange them in order smallest to greatest
We can see units for option A and B are in square inches so they represents area. So first we will find diameter from area using formula

so for choice (A) area is given as  . So plug this in A place in formula and then solve for radius r
. So plug this in A place in formula and then solve for radius r




3731.76 = r
So screw A will have 
 inches
 inches
Similarly for choice (E) area is 
 so again plug in formula





2.13201 = r
So screw E will have 
 inches
 inches
So diameters of all screws are as follows:
Screw A: 7463.52 inches
Screw B: 1.5 inches
Screw C:  inches
 inches
Screw D: 0.25 inches
Screw E: 4.26402 inches
Comparing all numbers 7463.52, 1.5, 1.875, 0.25, 4.26402 we can see that smallest number is 0.25, then comes 1.5, then 1.875 and then 4.26402 and then 7463.52
So order from least to greatest will be screw D (0.25), B(1.5), C(1.875), E (4.26402), A (7463.52).
So thats the order D,B,C,E,A and the final answer
