Cylinder Volume Calculator
Calculate the volume of a circular cylinder from radius or diameter and height.
How to Use the Cylinder Volume Calculator
Choose whether your measurement is a radius or diameter, enter that value and the cylinder height, then calculate. The tool applies the standard cylinder formula and returns both volume and circular base area.
Practical Example
If a cylinder has a radius of 4 units and a height of 10 units, its volume is π × 4² × 10, which is approximately 502.65 cubic units.
Factors That Affect the Result
The result depends on using accurate dimensions and consistent units. If you enter diameter instead of radius, the calculator divides it by two automatically. Rounding, measurement tolerance and irregular real-world shapes can also affect practical volume.
Frequently Asked Questions
What is the cylinder volume formula?
The formula is V = πr²h, where r is the radius and h is the height.
Can I enter a diameter instead of a radius?
Yes. Select diameter and the calculator converts it to radius before calculating.
What units does the result use?
The answer is in cubic units based on the measurement unit you used for radius or diameter and height.
