1. What is a Cylinder Volume Calculator?

Definition: This calculator computes the volume of a cylinder using its radius and height.

Purpose: It helps engineers, architects, students, and professionals determine the capacity or volume of cylindrical objects.

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, capacity planning, and structural design in various industries.

4. Using the Calculator

Tips: Enter the radius and height in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units?
A: Yes, but ensure both dimensions use the same unit (e.g., both in cm or both in inches).

Q2: What's the precision of the calculation?
A: The calculator uses PHP's pi() function and shows results to 3 decimal places.

Q3: How does diameter relate to this formula?
A: If you have diameter (D), divide it by 2 to get radius (r = D/2).

Q4: Can this calculate liquid capacity?
A: Yes, the volume result can represent liquid capacity when using appropriate units (e.g., liters if dimensions are in dm).

Q5: What about other cylinder types?
A: This formula works for right circular cylinders. For oblique cylinders, different formulas apply.
