MATH CALCULATOR
Diameter of Cone Calculator
Calculate the diameter of a cone using our easy-to-use online calculator.
What is the Diameter of Cone Calculator & How does it work?
The diameter of a cone is twice its radius. The radius can be calculated from the slant height and the height of the cone using the Pythagorean theorem: . Once the radius is determined, the diameter is simply twice the radius.
r = sqrt{frac{l^2 – h^2}{4}}
r = radius, l = slant height, h = height

Frequently Asked Questions
How do I calculate the radius of a cone if I know the slant height and height?
Use the formula r = √((l^2 – h^2) / 4), where l is the slant height and h is the height.
What is the relationship between the diameter and radius of a cone?
The diameter of a cone is twice its radius.
Can I use this calculator to find the diameter if I only know the slant height?
No, you need both the slant height and the height to calculate the radius and then the diameter.
How does the Pythagorean theorem apply to a cone?
The Pythagorean theorem (a^2 + b^2 = c^2) is used here with a as the radius, b as the height, and c as the slant height.
What units should I use when inputting values into this calculator?
Use consistent units for all measurements (e.g., all in centimeters or inches).
Is there a formula to calculate the diameter of a cone directly from the slant height and height?
Yes, once you have the radius using r = √((l^2 – h^2) / 4), the diameter is simply 2r.
What if I need to calculate the diameter of a cone for a project, but I don’t know the slant height or height?
You will need to measure or determine these dimensions first before using this calculator.
