Is the axis horizontal or vertical?
If it's horizontal:
Assuming the ends are flat:

Vol = [r^2*(arccos((r-h)/r) - (r-h)*sqrt(2rh- h^2)]*Length
= [29.5^2*arccos((29.5-20)/29.5) - (9.5)*sqrt(59*20 - 400)]*470
= [29.5^2*1.242919 - 9.5*27.92848]*470
= 816.33*470
= 383675 cubic inches
=~ 1661 gallons

The diameter of the base of a cylindrical milk tank is 59 in.
The length of the tank is 470 in.
The depth of the milk in the tank is 20 in.
What is the number of gallons of milk in the tank?
:
radius of the tank = 29.5 in
:
Find the vol of the milk (assume the tank is vertical)
V =
V = 54679.42 cu/inches
Change to cubic ft
V =
V = 31.64 cu/ft
Find the no. of gallons
31.64 * 7.481 = 236.7 gallons in the tank
