1. What is the Cylinder Volume Formula?

The cylinder volume formula calculates the volume of a cylinder in gallons using the radius and height in inches. The constant 0.004329 converts cubic inches to gallons.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

\[ V = \pi r^2 h \times 0.004329 \]

Where:

\( V \) — Volume in gallons
\( r \) — Radius in inches
\( h \) — Height in inches
\( \pi \) — Approximately 3.14159
0.004329 — Conversion factor (cubic inches to gallons)

Explanation: The formula calculates the volume in cubic inches first (πr²h) then converts it to gallons.

3. Importance of Volume Calculation

Details: Calculating cylinder volume is essential for determining liquid capacity in tanks, pipes, and other cylindrical containers in industries like engineering, manufacturing, and agriculture.

4. Using the Calculator

Tips: Enter radius and height in inches. Both values must be positive numbers. The calculator will automatically compute the volume in gallons.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 0.004329?
A: This converts cubic inches to US gallons (1 gallon = 231 cubic inches, so 1/231 ≈ 0.004329).

Q2: Can I use different units?
A: This calculator specifically uses inches for input and gallons for output. For other units, different conversion factors would be needed.

Q3: How accurate is the calculation?
A: The calculation is mathematically precise, assuming perfect cylindrical shape and accurate measurements.

Q4: Does this work for horizontal cylinders?
A: This formula is for vertical cylinders. Horizontal cylinders require a more complex calculation accounting for the liquid height.

Q5: What about irregular shapes?
A: This formula only works for perfect cylinders. Irregular shapes require different volume calculation methods.
