🔄 Cylinder Volume Calculator – Calculate Volume from Radius and Height
Need to calculate the volume of a cylinder? The Cylinder Volume Calculator computes the volume using the radius and height measurements, providing a step-by-step breakdown of the calculation process.
This guide explains what a cylinder is, how to calculate its volume, and walks you through using our free online cylinder volume calculator to solve geometry problems quickly and accurately.
📘 What Is a Cylinder?
A cylinder is a three-dimensional geometric shape with two parallel circular bases connected by a curved surface. Common examples include cans, pipes, tanks, and many containers we use in everyday life.
The key measurements of a cylinder are:
- Radius (r): The distance from the center of the circular base to any point on its edge
- Height (h): The perpendicular distance between the two circular bases
📏 How to Calculate a Cylinder's Volume
The standard formula for calculating a cylinder's volume is:
Volume = π × r² × h
Where:
- π (pi) is approximately 3.14159
- r is the radius of the circular base
- h is the height of the cylinder
The calculation can be broken down into these steps:
- Square the radius (r²)
- Multiply by π (π × r²) to get the area of the circular base
- Multiply by the height (π × r² × h) to get the volume

🧮 Example Cylinder Volume Calculations
Example 1: A cylinder with radius 5 cm and height 10 cm
Volume = π × 5² × 10
Volume = π × 25 × 10
Volume = π × 250
Volume ≈ 785.40 cm³
Example 2: A water tank with radius 1.5 m and height 3 m
Volume = π × 1.5² × 3
Volume = π × 2.25 × 3
Volume = π × 6.75
Volume ≈ 21.21 m³
