How to use this calculator
- Enter radius and height in the same units.
- Optionally label the unit.
- Read volume in cubic units.
- Use diameter/2 if you measured diameter.
Results explained
A right circular cylinder’s volume is the base area πr² times height. Keep units consistent so the answer is in cubic inches, centimeters, feet, etc.
Quick reference: cylinder volume
V = π r² h.
| Item | Detail |
|---|---|
| r = 3, h = 10 | V ≈ 282.74 |
| Diameter | r = d/2 |
| Surface area | Not computed here |
| Oblique cylinders | Different if not right |
Confirm units before treating this as a fill estimate.
How the estimate is built
V = π × r² × h.
Example scenario
r=3, h=10 → V ≈ 282.74 cubic units.
FAQ
Can I enter diameter?
Enter half the diameter as radius.
Liters from cm?
1,000 cm³ = 1 L.
Hollow pipe?
Subtract inner cylinder volume separately.
See sphere page?
Yes — for (4/3)πr³.
