Measuring the volume of a cylinder is easy. You just need to know a few things. In this guide, we will show you how.
What is a Cylinder?
A cylinder is a 3D shape. It has two circular bases and one curved side.

Parts of a Cylinder
- Base: The flat, circular surfaces.
- Height: The distance between the bases.
- Radius: The distance from the center to the edge of the base.
Formula for Cylinder Volume
The formula to find the volume of a cylinder is:
Steps to Measure Cylinder Volume
- Find the radius: Measure the distance from the center to the edge of the base.
- Measure the height: Measure the distance between the two bases.
- Square the radius: Multiply the radius by itself.
- Multiply by π: Use 3.14 for π.
- Multiply by height: Multiply the result by the height.
Example Calculation
Let’s say we have a cylinder with a radius of 3 cm and a height of 5 cm.
Step 3: Radius² = 3 × 3 = 9 cm²
Step 5: Volume = 3.14 × 9 × 5 = 141.3 cm³
Common Mistakes to Avoid
- Make sure to square the radius, not the diameter.
- Always use the same units for radius and height.
- Double-check your measurements.
Real-Life Applications
Knowing how to measure cylinder volume is useful. Here are some examples:
| Application | Description |

- Ruler: For small cylinders.
- Measuring Tape: For larger cylinders.
- Calculator: To perform the calculations.
Frequently Asked Questions
- What is the unit of volume?
- The unit of volume is cubic units, like cm³ or m³.
- Can I use a different value for π?
- You can use 3.14159 or 22/7 for more accuracy.
- Do I need to measure the diameter?
- No, measure the radius. The diameter is twice the radius.
Frequently Asked Questions
What Is The Formula For Cylinder Volume?
The formula is V = πr²h, where r is radius and h is height.
How Do You Measure Cylinder Radius?
Measure the distance from the center to the edge of the base.
How Do You Find The Height Of A Cylinder?
Measure the distance between the two bases of the cylinder.
Can You Use Diameter To Calculate Volume?
Yes, use diameter/2 to find the radius, then apply the volume formula.
Conclusion
