The unit u have to use to measure the amount of water in a swimming pool is in Liters :)
        
             
        
        
        
The perimeter is 166.9 ft.
Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)
once you get your answer, convert inches back to feet.
 
        
             
        
        
        
We have been given graph of circle V with radius 14 feet. We are asked to find the area of the circle V. 
We will use area of circle formula to solve our given problem.
 , where r represents radius of circle.
, where r represents radius of circle.
Upon substituting  in above formula, we will get:
 in above formula, we will get:




Therefore, the area of the circle V is  square feet and option 'c' is the correct choice.
 square feet and option 'c' is the correct choice.
 
        
             
        
        
        
If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.  
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.  
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and <span>(0.75, –2.25)
I am confused by the part, "</span><span>P is the length of the line segment from D".  Were you given a length P to help you determine which point.  Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given.  The image shows the distances I calculated and the graphed points. 
I hope this helps!</span>
