The sand we need to fill the cylinders is equal to the total volume of the six cylindrical posts .
Given terms ( common for each cylinder ) : 
- height (h) = 4 ft
- radius. (r) = 0.5 ft

Since volume of each cylinder is equal, so total volume of six cylindrical post :

Answer:
The confidence interval is   
Step-by-step explanation:
From the question we are told that 
   The sample size is  n  =  118  
    The  number that gave the correct answer is  k =  44 
 Generally the sample proportion is mathematically represented as 
       
=>     
Generally given that the confidence level is  95% the level of significance is mathematically represented as 
        
=>     
Generally from the normal distribution table the critical value  of   is
 is  
     
Generally the margin of error is mathematically represented as  
      
=>   
=>    
Generally 95% confidence interval is mathematically represented as  
              
=>     
=>   
 
        
             
        
        
        
Answer:
100 yds^2
Step-by-step explanation:
To find the area of a square, we need to know the length of one side of the square.  Since the perimeter is 4 times the length of one side, or 4s, and since 4s = 40 yds, s must be 10 yds.
Then the area of the square is (10 yds)^2 = 100 yds^2.
