1. What is the Cone Height Formula?

The cone height formula calculates the vertical height (h) of a right circular cone when you know the slant height (l) and the base radius (r). It's derived from the Pythagorean theorem applied to the right triangle formed by the radius, height, and slant height.

2. How Does the Calculator Work?

The calculator uses the cone height formula:

\[ h = \sqrt{l^2 - r^2} \]

Where:

Explanation: The formula comes from the right triangle relationship between the radius, height, and slant height of the cone.

3. Importance of Cone Height Calculation

Details: Knowing the height of a cone is essential for calculating its volume, surface area, and other geometric properties. It's used in engineering, architecture, and manufacturing.

4. Using the Calculator

Tips: Enter both slant height and radius in meters. Both values must be positive numbers, and the slant height must be greater than the radius.

5. Frequently Asked Questions (FAQ)

Q1: What if my slant height is less than the radius?
A: This is geometrically impossible for a right circular cone. The slant height must always be greater than the radius.

Q2: Can I use different units?
A: Yes, as long as both measurements use the same units. The result will be in those same units.

Q3: Does this work for oblique cones?
A: No, this formula only works for right circular cones where the apex is directly above the center of the base.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise, assuming perfect measurements of slant height and radius.

Q5: What's the relationship between height and slant height?
A: For a given radius, as height increases, slant height also increases, following the Pythagorean relationship.
