I can't really see the whole picture
A water tank is a cylinder
I don't know if there's anything like circumference of a cylinder but I know of area
The formula is
![2\pi \times r(r + h)](https://tex.z-dn.net/?f=2%5Cpi%20%5Ctimes%20r%28r%20%2B%20h%29)
where r=radius h=height
First of all you know it wiill be a positive slope as both the rise and the run are negative. a negative divided by a negative equals a positive. so you can plot the points (2,3) and (-2,-3) as they will be points on this line. next you take a straight line and place it so that both points are intercepted. then extend the line outwards.
