1. What is Cylinder Volume Calculation?

Definition: This calculator computes the volume of a cylinder in cubic millimeters based on its radius and height.

Purpose: It helps engineers, designers, and students determine the capacity or space occupied by cylindrical objects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic millimeters)
• \( r \) — Radius (millimeters)
• \( h \) — Height (millimeters)
• \( \pi \) — Pi constant (~3.14159)

Explanation: The formula calculates the base area (πr²) and multiplies it by the height to get the total volume.

3. Importance of Cylinder Volume Calculation

Details: Accurate volume calculations are essential for material estimation, capacity planning, and engineering designs involving cylindrical components.

4. Using the Calculator

Tips: Enter the radius and height in millimeters. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for other units?
A: This calculator specifically uses millimeters. For other units, convert values to mm first or use a different calculator.

Q2: What's the precision of the calculation?
A: Results are shown to 3 decimal places, using PHP's built-in π constant precision.

Q3: Does this work for hollow cylinders?
A: No, this calculates solid cylinder volume. For hollow cylinders, subtract the inner cylinder volume from the outer.

Q4: How do I convert mm³ to other units?
A: 1,000 mm³ = 1 cm³, 1,000,000 mm³ = 1 dm³, 1,000,000,000 mm³ = 1 m³.

Q5: What's the maximum size this can calculate?
A: There's no theoretical limit, but extremely large numbers may show scientific notation.
