1. What is Cylinder Volume?

The volume of a cylinder is the amount of space it occupies, calculated using its radius and height. It's fundamental in many engineering, physics, and everyday applications.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

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

Where:

\( V \) — Volume (units³)
\( r \) — Radius of the base (units)
\( h \) — Height of the cylinder (units)
\( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula multiplies the area of the circular base (πr²) by the height (h) to get the total volume.

3. Importance of Volume Calculation

Details: Calculating cylinder volume is essential in many fields including engineering (pipe capacity), chemistry (reaction vessels), and everyday measurements (liquid containers).

4. Using the Calculator

Tips: Enter radius and height in the same units. Both values must be positive numbers. The result will be in cubic units of whatever unit you used for input.

5. Frequently Asked Questions (FAQ)

Q1: What if my cylinder is not perfect?
A: This formula assumes a perfect right circular cylinder. For irregular shapes, other methods like integration may be needed.

Q2: Can I use different units for radius and height?
A: No, both measurements must be in the same units for the calculation to be valid.

Q3: How accurate is π in this calculation?
A: The calculator uses PHP's pi() function which is accurate to about 14 decimal places.

Q4: What's the difference between diameter and radius?
A: Radius is half the diameter. Make sure you're using the correct measurement in the formula.

Q5: Can this calculate partial cylinder volumes?
A: This calculates total volume. For partial volumes (like liquid in a tank), you'd need additional information about the fill level.
