1. What is the Cylinder Radius Formula?

The cylinder radius formula calculates the radius of a cylinder when you know its volume and height. This is derived from the basic volume formula for a cylinder.

2. How Does the Calculator Work?

The calculator uses the cylinder radius formula:

\[ r = \sqrt{\frac{v}{\pi \times h}} \]

Where:

\( r \) — Radius of the cylinder
\( v \) — Volume of the cylinder
\( h \) — Height of the cylinder
\( \pi \) — Pi constant (~3.14159)

Explanation: The formula rearranges the standard cylinder volume formula \( v = \pi r^2 h \) to solve for radius.

3. Importance of Cylinder Dimensions

Details: Calculating cylinder dimensions is essential in engineering, manufacturing, and various scientific applications where precise measurements are required.

4. Using the Calculator

Tips: Enter volume in cubic units and height in units. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use consistent units for both volume and height. The result will be in the same linear unit as your height measurement.

Q2: Can I calculate height if I know radius and volume?
A: Yes, the formula would be \( h = v / (\pi r^2) \).

Q3: What's the precision of this calculator?
A: Results are rounded to 4 decimal places, but internal calculations use higher precision.

Q4: Does this work for other cylinder-like shapes?
A: This formula is specific to right circular cylinders. Other shapes may require different formulas.

Q5: What if my cylinder is not perfect?
A: This formula assumes a perfect geometric cylinder. For irregular shapes, more complex calculations are needed.
