1. What is a Cylinder Volume Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic meters)
• \( r \) — Radius of the base (meters)
• \( h \) — Height of the cylinder (meters)
• \( \pi \) — Mathematical constant (~3.14159)

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

3. Importance of Cylinder Volume Calculation

Details: Accurate volume calculations are essential for material estimation, fluid capacity, structural design, and scientific measurements.

4. Using the Calculator

Tips: Enter the radius and height in meters. Both values must be positive numbers. The result will be in cubic meters (m³).

5. Frequently Asked Questions (FAQ)

Q1: What if my measurements are in centimeters?
A: Convert to meters first (divide by 100) before using the calculator.

Q2: Does this work for pipes and tubes?
A: Yes, this calculates the total volume. For hollow cylinders, you'll need to subtract the inner volume.

Q3: How precise is the calculation?
A: The calculator uses PHP's M_PI constant (about 15 digits of precision) and shows results to 3 decimal places.

Q4: Can I calculate diameter instead of radius?
A: Yes, just divide your diameter measurement by 2 to get the radius.

Q5: What's the practical application of this calculation?
A: Useful for determining concrete needed for cylindrical columns, water tank capacities, pipe volumes, and more.
