How many gallons of water can be stored in a cylindrical tan

How many gallons of water can be stored in a cylindrical tank 35 feet high and 12 feet in diameter?

Solution

Volume of the cylinder tank is given by pi*r^2 *h

r = 12/2 = 6 ft

h = 35 ft

So, volume = 3.14*(12^2)*35

=15825.6 ft^3

1 cubic ft = 7.48 gallons

15825.6 = 118375.5 gallons of water in cylcinder tank can be stored.
