What is the Cylinder Area Calculator?
The cylinder area calculator is a free online tool that helps you work out cylinder area quickly and accurately. It uses the standard formula Volume = pi x r^2 x h; Surface = 2 pi r (r + h) and shows the result instantly as you type, along with a full breakdown so you can see exactly how the answer was reached.
How to use this calculator
- Enter radius and height.
- See volume and surface area.
Formula used
Volume = pi x r^2 x h; Surface = 2 pi r (r + h)Explanation of each input
- Radius (units) โ the radius used in the calculation.
- Height (units) โ the height used in the calculation.
Understanding your result
- Volume โ the calculated volume in cu units.
- Surface area โ the calculated surface area in sq units.
Step-by-step calculation
For the example values r 3, h 10:
- Apply the formula:
Volume = pi x r^2 x h; Surface = 2 pi r (r + h) - Substitute the values: pi x 9 x 10
- Result: Volume about 282.74
Worked example
| Inputs | r 3, h 10 |
|---|---|
| Working | pi x 9 x 10 |
| Result | Volume about 282.74 |
