Question

If you have an old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall, how many cubic feet of water does it hold?

Answer 1

Answer:

The old fish tank hold 18.84 cubic feet of water.

Step-by-step explanation:

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 ($r$) = $\frac{Diameter}{2}=\frac{2}{2}=1\ feet.$

Height ($h$) = $6\ feet.$

Now, to get the cubic feet off water the tank hold we put formula:

(Taking the value of π as 3.14.)

$Volume=\pi r^2h\\\\Volume=3.14\times 1^2\times 6\\\\Volume=3.14\times 1\times 6\\\\Volume=18.84\ cubic feet.$

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