1. What is the Height of Frustum of Cone?

The height of a frustum of a cone is the perpendicular distance between the two parallel bases of the frustum. It is an important geometric measurement used in various engineering and architectural applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{TSA - A_{top} - A_{base}}{\pi (r_{top} + r_{base})} \]

Where:

\( h \) — Height of the frustum
\( TSA \) — Total surface area of the frustum
\( A_{top} \) — Area of the top circular base
\( A_{base} \) — Area of the bottom circular base
\( r_{top} \) — Radius of the top circular base
\( r_{base} \) — Radius of the bottom circular base
\( \pi \) — Mathematical constant (approximately 3.14159)

Explanation: This formula calculates the height by subtracting the areas of the two circular bases from the total surface area and dividing by the circumference of the average of the two radii.

3. Importance of Height Calculation

Details: Calculating the height of a frustum is crucial in various applications including construction, manufacturing, and geometric modeling. It helps determine volume, surface area, and other important geometric properties.

4. Using the Calculator

Tips: Enter all values in consistent units. Ensure all values are positive numbers. The sum of top and base radii must be greater than zero for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a frustum of a cone?
A: A frustum of a cone is the portion of a cone that remains after cutting off the top by a plane parallel to the base.

Q2: Why is the height calculation important?
A: Height is a fundamental dimension needed to calculate volume, surface area, and other geometric properties of the frustum.

Q3: What units should I use?
A: Use consistent units throughout (e.g., all in meters, all in inches). The calculator will return height in the same unit system.

Q4: Can this calculator handle different unit systems?
A: Yes, as long as all input values use the same unit system, the result will be in the same units.

Q5: What if I get a negative height result?
A: A negative height indicates invalid input values. Check that TSA is greater than the sum of top and base areas, and all values are positive.
