Question 259365: an 8-foot tall cylindrical water tank has a base of diameter 6 feet.
how much water is in the tank if the water is 5 feet deep?
what is the formula for the volume of water as a function of its depth in the tank?

You can put this solution on YOUR website!
Depth and height are the same thing. Height is looking from the bottom and depth from the top
V=pi*r^2*h
V==pi*3^2*5 volume of water at 5 ft deep.
V=pi*9*5
V=45*pi
pi=about 3.14
radius =1/2 diameter
Why didn't we use 8 ft for the height ?
We didn't fill the tank all the way but only to 5 ft.
