~~~~~~~~~~~~~~~~~~ 
A ( - 7 , - 9 ) 
B ( x , y ) 
M ( - 0.5 , - 3 ) 
 = - 0.5 ⇒ <em>x = 6</em>
 = - 0.5 ⇒ <em>x = 6</em> 
 = - 3 ⇒ <em>y = 3</em>
 = - 3 ⇒ <em>y = 3</em>

Answer:
1,000,000
Step-by-step explanation:
1mm=1e-6km
10mm=1e-5km
100mm=1e-4km
1000mm=000.1km
10000mm=0.01km
100000mm=0.1km
500000mm=0.5km
1000000mm=1km
 
        
             
        
        
        
Using conversion of units and volume of a cylinder, it is found that 23.17 cubic yards of concrete are needed, option D.
The volume of a cylinder of radius r and height h is given by:

In this problem:
- We want the volume in cubic yards, thus, the units of radius and height have to be in yards.
- 32 inches in diameter, thus 16 inches of radius. Since each inch has 0.0278 yards, this is a radius of 0.44 yards, thus  . .
- Height of 8 feet, and since each feet has 0.33 yards, this is a height of 2.67 yards, thus  
- 14 poles, thus the volume is multiplied by 14.
Then:

23.17 cubic yards of concrete are needed, option D.
