What is the Volume of a Cone?

The volume of a cone represents the amount of three-dimensional space enclosed within a cone. Our volume of a cone calculator uses the fundamental formula V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone. Understanding cone volume is essential in geometry, engineering, and real-world applications.

A cone is a three-dimensional geometric shape with a circular base that tapers to a single point called the apex or vertex. The volume calculation helps determine how much material or liquid the cone can hold, making it crucial for manufacturing, construction, and scientific applications.

Volume of a Cone Formula

V = (1/3)πr²h

Where:

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

This volume of a cone calculator formula is derived from the general formula for the volume of a pyramid, which is one-third the base area times the height. Since a cone has a circular base, we use πr² for the base area, resulting in the final formula used by our calculator.

Volume of a Cone Calculator Examples

Example 1: Ice Cream Cone

Given:

• Radius = 3 cm
• Height = 12 cm

Solution:

V = (1/3)π(3)²(12)

V = (1/3)π(9)(12)

V = (1/3)π(108)

V = 113.10 cm³

Example 2: Traffic Cone

Given:

• Radius = 15 cm
• Height = 70 cm

Solution:

V = (1/3)π(15)²(70)

V = (1/3)π(225)(70)

V = (1/3)π(15,750)

V = 16,493.36 cm³

Frequently Asked Questions

How accurate is this volume of a cone calculator?

Our volume of a cone calculator provides highly accurate results using precise mathematical formulas. The calculator uses the standard cone volume formula and maintains precision up to several decimal places for professional and educational use.

What units can I use with the calculator?

The calculator supports various units including centimeters, meters, inches, feet, and more. You can input measurements in any unit, and the calculator will provide results in the same unit cubed (e.g., cm³, m³, in³, ft³).

Can I calculate the volume of a truncated cone?

This calculator is designed for complete cones. For truncated cones (cones with the top cut off), you would need to calculate the volume of the complete cone and subtract the volume of the removed top portion.

What's the difference between radius and diameter?

The radius is the distance from the center of the circular base to its edge, while the diameter is twice the radius (the distance across the entire circle through the center). Our calculator uses radius in the formula, so if you have the diameter, divide it by 2.
