About Cylinder Calculator
The Cylinder Volume Calculator computes the 3D space contained within a right circular cylinder. Cylinders are one of the most common geometric primitives, heavily used in fluid storage (tanks, pipes) and engine displacement.
How Cylinder Calculator Works
- Step 1: Radius & Height: Input the radius of the circular base and the straight vertical height of the cylinder.
- Step 2: Calculate: The tool calculates the area of the base (πr²) and multiplies it by the height.
Frequently Asked Questions
What if I have the diameter instead of the radius?
Simply halve your diameter to get the radius before using the calculator.
Does this calculate the surface area?
This specific tool calculates Volume. Calculating surface area requires adding the area of the two circular caps to the lateral surface area.
Can it calculate liquid capacity?
Yes! If you input dimensions in centimeters, your result is in cubic centimeters (cm³), which is exactly equivalent to milliliters (mL).
