1. What is the Cylinder Height Formula?

The cylinder height formula calculates the height (or length) of a cylinder when you know its volume and radius. It's derived from the basic volume formula for a cylinder: V = πr²h.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The formula rearranges the standard cylinder volume equation to solve for height instead of volume.

3. Importance of Height Calculation

Details: Calculating cylinder height is essential in engineering, manufacturing, and various scientific applications where dimensional analysis is required.

4. Using the Calculator

Tips: Enter volume in cubic units and radius in length units. Both values must be positive numbers. The result will be in the same length units as your radius input.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use consistent units - if radius is in meters, volume should be in cubic meters, and height will be in meters.

Q2: Does this work for tubes (hollow cylinders)?
A: No, this formula is for solid cylinders. For tubes, you'd need to account for both inner and outer radii.

Q3: How precise is the calculation?
A: The precision depends on your input values. The calculator uses π to high precision (about 15 decimal places).

Q4: Can I use diameter instead of radius?
A: Yes, but you'll need to divide the diameter by 2 first since the formula requires radius.

Q5: What if my cylinder isn't perfect?
A: This formula assumes a perfect right circular cylinder. For irregular shapes, more complex calculations are needed.
