1. What is the Height of Frustum of Cone given Total Surface Area?

The height of a frustum of a cone given its total surface area is the vertical distance between the two parallel bases of the frustum when the total surface area and the radii of both bases are known. This calculation is essential in geometry and various engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{\sqrt{\left(\frac{TSA - \pi (r_1^2 + r_2^2)}{\pi (r_1 + r_2)}\right)^2 - (r_1 - r_2)^2}} \]

Where:

\( h \) — Height of the frustum
\( TSA \) — Total surface area of the frustum
\( r_1 \) — Top radius of the frustum
\( r_2 \) — Bottom radius of the frustum
\( \pi \) — Mathematical constant pi (approximately 3.14159)

Explanation: The formula derives from the relationship between the total surface area, the lateral surface area, and the geometry of the frustum.

3. Importance of Height Calculation

Details: Calculating the height of a frustum is crucial in various fields including architecture, engineering, and manufacturing where conical frustum shapes are commonly used in structures, containers, and mechanical parts.

4. Using the Calculator

Tips: Enter the total surface area in square meters, both radii in meters. All values must be positive numbers, and the sum of radii cannot be zero.

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: Can this calculator handle different units?
A: The calculator uses meters for length and square meters for area. Convert your measurements to these units before calculation.

Q3: What if I get an imaginary number result?
A: An imaginary result indicates that the input values are not physically possible for a frustum shape. Check your measurements.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact based on the input values. The accuracy depends on the precision of your measurements.

Q5: Can I use this for truncated pyramids?
A: This formula is specifically for conical frustums. Different formulas apply for pyramidal frustums.
