How to Use the Cylinder Volume Calculator
This calculator computes the volume, lateral surface area, and total surface area of a right circular cylinder based on its radius and height.
Step-by-Step Instructions
- Enter the Radius (r) – Type a positive number in the Radius field (e.g., 5).
- Enter the Height (h) – Type a positive number in the Height field (e.g., 10).
- Select the Unit – Choose from cm, m, in, or ft. The result will display with the corresponding cubic (³) or square (²) unit.
- Click "Calculate" – The results will appear below, showing:
- Volume (V = πr²h)
- Lateral Area (Alateral = 2πrh)
- Total Surface Area (Atotal = 2πrh + 2πr²)
- Review the Formula – The exact calculation with your inputs is displayed for verification.
Important Notes
- Both radius and height must be positive numbers (greater than zero).
- You can use decimal values (e.g., 2.5) for more precise measurements.
- The calculator works with any unit (metric or imperial) – just select the appropriate one before calculating.
- If you enter invalid data, the fields will highlight in red, and results will show a dash.
