1. What is a Cylinder Volume Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of cylinder (cubic inches)
• \( r \) — Radius of the base (inches)
• \( h \) — Height of the cylinder (inches)
• \( \pi \) — 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 design specifications in various engineering and manufacturing applications.

4. Using the Calculator

Tips: Enter the radius and height in inches. Both values must be positive numbers. The result will be in cubic inches.

5. Frequently Asked Questions (FAQ)

Q1: What if I have diameter instead of radius?
A: Simply divide the diameter by 2 to get the radius before entering the value.

Q2: Can I use this for metric measurements?
A: This calculator is specifically for inches. For centimeters, multiply the result by 16.387 to convert to cm³.

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

Q4: How precise is the calculation?
A: The calculator uses PHP's pi() function which provides sufficient precision for most practical applications.

Q5: What's the practical use of this calculation?
A: Useful for determining liquid capacity, material requirements, displacement volumes, and storage capacities of cylindrical containers.
