Answer: 57.1 (rounded)
Step-by-step explanation:
Area of triangle formula: 1/2 x base x height
Area of a semicircle: 1/2 x pi x r^2
(1/2 x 8 x 8) + (1/2 x pi x 4^2)
= 57.1 (rounded)
 
        
             
        
        
        
Answer:
The work done to  pump all of the kerosene from the tank to an outlet is  
  
Step-by-step explanation:
The work is defined by:
 (1)
 (1)    
The force here will be the product between the volume and the kerosene weighing, so we have :

This force will be in-lbs.
 Where R is the radius (3 feet)                     
Then using (1), we have:
 
   
Here 8-y is a distance at some point of the tank. Now, to get the work done from the base to the top of the tank we will need to take integral from 0 to 8 feet.
 
 


 
  


Therefore, the work done to  pump all of the kerosene from the tank to an outlet is  
  
I hope it helps you!
