Cone Calculator
Calculate cone volume, surface area, and slant height from radius and height
About this calculator
The Cone Calculator is a powerful tool that helps you instantly calculate three essential cone measurements: volume, surface area, and slant height. By simply entering the radius and height of any cone, this calculator provides accurate results for geometry homework, engineering projects, construction planning, or manufacturing applications. Whether you're a student learning about 3D shapes, an architect designing conical structures, or a craftsperson creating cone-shaped objects, this calculator eliminates complex manual calculations and reduces errors.
How to use
Enter the radius (distance from center to edge of the base) and height (vertical distance from base to apex) of your cone into the input fields. The calculator will automatically compute and display the volume, total surface area, and slant height using standard geometric formulas. All measurements should be in the same units for accurate results.
Frequently asked questions
What is slant height and why is it important?
Slant height is the diagonal distance from the base edge to the cone's tip. It's crucial for calculating surface area and material requirements for cone construction.
Can I use this calculator for truncated cones?
No, this calculator is designed for complete cones only. Truncated cones (cone frustums) require different formulas and a specialized calculator.
What units can I use with this calculator?
You can use any units (inches, centimeters, meters, etc.) as long as both radius and height use the same unit. Results will be in corresponding square and cubic units.
