Given:
An old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall.
Now, to find the cubic feet of water the fish tank hold.
Dimensions of old fish tank are:
Diameter is 2 feet so. we find the radius first.
Radius (
) =

Height (
) =

Now, to get the cubic feet off water the tank hold we put formula:
(Taking the value of π as 3.14.)

Therefore, the old fish tank hold 18.84 cubic feet of water.
