How many gallons are held in a tank that is 2 inches by 25 feet?

To determine the volume of a cylindrical tank, the formula used is:

Volume (V) = π × r² × h

Where:

• π (pi) is approximately 3.14,

• r is the radius of the tank,

• h is the height (or length, when the tank is horizontal).

In this case, we convert the dimensions given into consistent units and substitute them into the formula. The tank has a diameter of 2 inches, which means the radius (r) is 1 inch (2 inches / 2). The height of the tank is 25 feet. We need to convert these dimensions into the same units for the calculation.

First, we convert the radius from inches to feet since the height is in feet:

1 inch = 1/12 feet, so the radius becomes:

1 inch = 0.0833 feet.

Next, we use the height of the tank:

Height (h) = 25 feet.

Now substituting these dimensions into the volume formula:

V = π × (0.0833 feet)² × 25 feet

= π × 0.006944 square feet × 25 feet

= π × 0.1736 cubic feet.
