Introduction: What is Cylinder Volume and Why It Matters
Ever wondered how much water your cylindrical water tank can hold? Or how much concrete you'll need to fill a round column? That's where cylinder volume comes in! Volume tells you the space inside a 3D shape - in this case, a soda can-like object with two circular bases. Whether you're a DIY enthusiast, student, or engineer, calculating cylinder volume helps with tasks like:
- Measuring liquid capacity (e.g., aquariums, fuel tanks)
- Estimating materials for construction or crafts
- Solving geometry problems quickly
Our Cylinder Volume Calculator lets you skip manual math - just plug in the radius and height to get instant results in cubic feet, gallons, liters, or other units.
How to Calculate the Volume of a Cylinder
Follow this simple 3-step process:
- Measure the radius (r) - Half of your cylinder's diameter
- Measure the height (h) - Vertical distance between bases
- Use the formula: V = π × r² × h
Example Calculation
For a cylinder with 3-inch radius and 10-inch height:
V = 3.1416 × 3² × 10 = 282.74 cubic inches
Formula for Volume of a Cylinder Explained
Let's break down V = πr²h:
- r (Radius): Half the width of the circular base
- h (Height): Distance between the two bases
- π (Pi): Mathematical constant (~3.14159)
Why it works: πr² calculates the base area, which we multiply by height to get 3D space.

Converting Volume to Gallons and Cubic Feet
Cubic Feet to Gallons
Multiply by 7.48052:
5 ft³ × 7.48052 = 37.4 gallons
Cubic Inches to Gallons
- Convert to cubic feet: Volume ÷ 1728
- Multiply by 7.48052
Surface Area of a Cylinder Calculator
Need to calculate exterior surface area? Use this formula:
Surface Area = 2πr(h + r)
Example: For r=3" and h=10":
2 × 3.1416 × 3 × (10 + 3) = 245.04 in²
