Answer:  -0.89  1-21 0.4 1/2 9/8
Step-by-step explanation:
 
        
                    
             
        
        
        
10in = 0.833333ft^2 that is the total amount for one side. For a cube that has 6 sides, you multiply 0.833333 by 6.
You need <span>4.999998ft^2 of paper</span>
        
             
        
        
        
It would be 50.24 ft
BTW in this case I used 3.14 for pi
        
                    
             
        
        
        
The coordinates of D are (-3, -7)
First we need to find the coordinates of B. In order to do that we simply take the average of the two points that make up the segment for which it is the midpoint (A and C). 
Average of x's
-9 + -1 = -10/2 = -5
Average of y's
-4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1). 
Now we can find D by noting the E will be the average of B and D. So we can use the average equation to determine the values of D. 
Average of x's
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of y's
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
Now we know the coordinates of D to be (-3, -7)
