1. What is the Volume of a Cylindrical Tank?

Definition: This calculator computes the volume of a cylindrical tank based on its radius and height.

Purpose: It helps engineers, architects, and designers determine the capacity of cylindrical containers, tanks, or pipes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic units)
• \( r \) — Radius of the base (units)
• \( h \) — Height of the cylinder (units)
• \( \pi \) — 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 Cylindrical Volume Calculation

Details: Accurate volume calculations are essential for storage capacity planning, material requirements, and structural design.

4. Using the Calculator

Tips: Enter the radius and height in the same units. The result will be in cubic units of the same measurement system.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: You can use any units (meters, feet, inches) as long as both radius and height use the same units.

Q2: Does this work for partially filled tanks?
A: No, this calculates total volume. For partial fills, you would need additional calculations.

Q3: How accurate is the π value used?
A: PHP's pi() function provides sufficient accuracy (about 15 decimal places) for most practical applications.

Q4: Can I calculate diameter instead of radius?
A: Yes, just divide your diameter by 2 before entering it as the radius.

Q5: What about the thickness of the tank walls?
A: This calculates internal volume. For material calculations, you would need to account for wall thickness separately.
