Cylinder Volume Calculator
Calculate the volume of a perfect cylinder easily using radius and height.
What is a Cylinder?
A 3D shape with two parallel circular bases.
A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. The most common type is a right circular cylinder.
How to Find the Volume of a Cylinder
You need the radius of the base and the height.
Cylinder Volume Formula
The equation for a cylinder's volume.
Where 'V' is volume, 'π' is roughly 3.14159, 'r' is the base radius, and 'h' is the height.

Frequently Asked Questions
What if I only have the diameter?
Divide the diameter by 2 to get the radius, then use the standard formula.
How do I calculate the capacity of a cylindrical tank?
Measure the inner radius and inner height of the tank, use the cylinder volume formula, and convert the cubic units into liters or gallons.
What is a right cylinder versus an oblique cylinder?
A right cylinder has bases aligned directly above each other. An oblique cylinder leans to one side, but surprisingly, the volume formula remains exactly the same.
Can I use this for an oval cylinder?
No, if the base is an oval (ellipse), you must use the formula for an elliptical cylinder: V = π × a × b × h, where a and b are the major and minor radii.
