## RN Calculator

This calculator helps you determine the mass of a right circular cylinder based on its radius, height, and material density.

### How to Use the RN Calculator

- Enter the radius (r) of the cylinder in the corresponding input field.
- Enter the height (h) of the cylinder in the corresponding input field.
- Enter the density (ρ) of the material in the corresponding input field.
- Click on the “Calculate” button to obtain the result.

### How the Calculation Works

The mass of the cylinder is calculated using the formula:

Mass = Volume × Density

Where the volume (V) of a right circular cylinder is calculated using the formula:

Volume = π × r² × h

You then multiply the volume by the density (ρ) of the material to get the mass of the cylinder.

### Limitations

- Ensure all inputs are positive numbers.
- Invalid or negative inputs will not provide correct results.
