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:

  1. Measure the radius (r) - Half of your cylinder's diameter
  2. Measure the height (h) - Vertical distance between bases
  3. 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

  1. Convert to cubic feet: Volume ÷ 1728
  2. 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
