What is the Volume of a Cylinder?

The volume of a cylinder refers to the amount of space inside the cylindrical shape. The volume can be calculated using the following formula:

V = π * r² * h

Where:

• V = Volume of the cylinder
• π = Pi (approximately 3.14159)
• r = Radius of the base of the cylinder
• h = Height of the cylinder

This formula works because the volume of a cylinder is the area of the circular base (π * r²) multiplied by the height of the cylinder (h).

How to Use Our Cylinder Volume Calculator

Our online volume of a cylinder calculator is easy to use. Here’s a step-by-step guide to help you get started:

1. Enter the Radius (r):
   • Input the radius of the circular base of the cylinder. For example, if the radius is 4 cm, enter “4.”
2. Enter the Height (h):
   • Input the height of the cylinder. If the height is 10 cm, enter “10.”
3. Click “Calculate”:
   • After entering both the radius and height, click the “Calculate” button, and the calculator will instantly provide you with the volume of the cylinder.
4. View Your Result:
   • The result will show the volume in cubic units (e.g., cubic centimeters or cubic inches) depending on the units you’ve entered.

Example 1: Volume of a Cylinder

Let’s calculate the volume of a cylinder with the following dimensions:

• Radius (r) = 3 cm
• Height (h) = 5 cm

Using the formula:

V = π * r² * h

V = 3.14159 * (3)² * 5

V = 3.14159 * 9 * 5

V ≈ 141.37 cm³

So, the volume of the cylinder is approximately 141.37 cubic centimeters (cm³).

Example 2: Volume of a Large Tank

Let’s say you want to calculate the volume of a large cylindrical water tank. The dimensions are:

• Radius (r) = 2 meters
• Height (h) = 8 meters

Using the formula:

V = π * r² * h

V = 3.14159 * (2)² * 8

V = 3.14159 * 4 * 8

V ≈ 100.53 m³

So, the volume of the tank is approximately 100.53 cubic meters (m³). This is the amount of space the tank can hold, useful for determining its water capacity.

Frequently Asked Questions (FAQ)

1. What is the formula to calculate the volume of a cylinder?

The formula for calculating the volume of a cylinder is:

V = π * r² * h

Where:

• V is the volume
• r is the radius of the circular base
• h is the height of the cylinder

2. What units do I use when calculating the volume of a cylinder?

The units you use for radius and height will determine the units of the volume. If you enter the radius in centimeters and the height in centimeters, the result will be in cubic centimeters (cm³). If you use meters, the volume will be in cubic meters (m³).

3. Can I use this calculator for cylinders with different units?

Yes! You can use our cylinder volume calculator with different units, as long as you make sure that both the radius and height are in the same units. The calculator will then output the volume in cubic units corresponding to the ones you entered.

4. How accurate is the volume calculator?

Our cylinder volume calculator is extremely accurate. The formula used is based on the mathematical constant π, which is rounded to a high degree of precision. For most practical purposes, this level of accuracy is more than sufficient.

5. What if I don’t know the radius, but I have the diameter of the cylinder?

No problem! If you know the diameter of the cylinder, simply divide it by 2 to get the radius. Then you can proceed with the calculation as usual.
