Answer: 14.32 degrees
The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers
A full perimeter </span>of the circle, which is 25.14km,  has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°
        
             
        
        
        
Answer:
Minimum total cost = $20550
 maximum revenue $44,100
Step-by-step explanation:
Given data:
Production cost $5.55 per unit
Fixed cost = $15000 per month
Price, p = 42-0.01 q
where. q represent number of unit produced
revenue can be wriiten as
p.q =  42q - 0.01q^2
1) from information 1000 unit has to produced therefore 
total cost = 15000 + 5.55×1000 = $20550
Minimum total cost = $20550
2) Revenue  =  42q - 0.01q^2

therefore  for maximum revenue q is = 2100
so, maximum revenue 
                                       =  $44,100
