1. What is the Cylinder Density Formula?

The density of a cylinder is calculated by dividing its mass by its volume. For a cylinder, the volume is calculated as π multiplied by the square of the radius multiplied by the height.

2. How Does the Calculator Work?

The calculator uses the cylinder density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass of the cylinder (kg)
• \( r \) — Radius of the cylinder (m)
• \( h \) — Height of the cylinder (m)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula calculates how much mass is contained in each unit volume of the cylinder.

3. Importance of Density Calculation

Details: Density is a fundamental physical property used in material science, engineering, and physics to characterize materials and predict their behavior under different conditions.

4. Using the Calculator

Tips: Enter mass in kilograms, radius and height in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: The calculator expects mass in kilograms (kg) and radius/height in meters (m) for density in kg/m³.

Q2: Can I use this for hollow cylinders?
A: No, this formula calculates the average density of a solid cylinder. For hollow cylinders, you need to account for the empty space.

Q3: What is a typical density range for common materials?
A: Densities vary widely - from about 0.001 g/cm³ (aerogels) to 22.6 g/cm³ (osmium). Water is 1 g/cm³ (1000 kg/m³).

Q4: How does temperature affect density?
A: Most materials expand when heated, decreasing their density. The effect is more pronounced in gases than solids.

Q5: Can I calculate mass if I know density and dimensions?
A: Yes, you can rearrange the formula: \( m = \rho \times \pi r^2 h \).
