1. What is the Diameter of Hemisphere?

The diameter of a hemisphere is the straight line passing through the center of the hemisphere and connecting two opposite points on its circular base. It is twice the length of the radius of the hemisphere.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( D \) — Diameter of Hemisphere (m)
• \( r \) — Radius of Hemisphere (m)

Explanation: The diameter is simply twice the radius, as the diameter spans the entire width of the hemisphere through its center.

3. Importance of Diameter Calculation

Details: Calculating the diameter of a hemisphere is essential in various geometric and engineering applications, including volume calculations, surface area determinations, and structural design where hemispherical shapes are involved.

4. Using the Calculator

Tips: Enter the radius of the hemisphere in meters. The value must be positive and valid (radius > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between diameter and radius?
A: The diameter is exactly twice the radius of the hemisphere (D = 2r).

Q2: Can I calculate radius from diameter?
A: Yes, the radius can be calculated by dividing the diameter by 2 (r = D/2).

Q3: Does this formula work for both solid and hollow hemispheres?
A: Yes, the diameter calculation is the same for both solid and hollow hemispheres as it only depends on the outer dimensions.

Q4: What units should I use for the calculation?
A: The calculator uses meters, but the formula works with any consistent unit system (cm, mm, inches, etc.).

Q5: How accurate is this calculation?
A: The calculation is mathematically exact, assuming the input radius is accurate.
