How do i figure out ratios i really am struggling on this topic

have done the calculus which reveals that the surface area is at a minimum when height is double the radius. I am now trying to find an equation for the relationship between the amount of wasted surface area as a percentage of the minimum surface area and the ratio between height and radius. If I were to plot it on a graph, the y axis would be the percentage of excess materials needed as a percentage of the minimum possible surface area, and the x axis would be height divided by radius. Since the surface area is minimized when height=2(radius), I know that when x=2, y=0. The website https://www.datagenetics.com/blog/august12014/index.html explains what I am trying to do quite well and shows the graph below. I am trying to find the equation for this graph, but am unsure how to go about it.

take home "B" and get a raise of "C". how do I figure out the new Take Home of "X"

10,4,10,0 = 24/4 = 6 average return Don’t add up because it 0 Square the number: 10-6=4^2= 16 4-6 = -2^2= 4 10-6=4^2 = 16 0-6 = -6^2 = 36 =72 sum of square of diff of mean /3=24 Square root 24 = 4.9 24= variance 4.9= standard deviation 20,2,2,0 = 24/4= 6 average return 20-6 = 14 = 196 2-6 = -4 =16 2-6 = -4 = 16 0-6 = -6 = 36 = 256 – variance Square root 256 = 14.6 = standard deviation

e able to figure out the flow in a pipe system. The pipe system is pretty small. I have attached a document explaining everything that I need to do. The main thing that I don’t know how to do is to figure out what pipe sizes I need based off of my water demand calculation. I need this to get done ASAP so please help.
