Given information
The shape of the water tank is given as follows:
Step-by-step explanation
Step 1.
At a depth h from the top of the tank, its height with respect to the bottom is 8-h
The differential radius of the tank at any level is proportional to the height at that level.
So, find the radius r at any depth h, by equating the ratio of widths and heights.
