1. What is the Area of Half Yin-Yang?

The Area of Half Yin-Yang refers to the amount of space occupied by half of the Yin-Yang symbol, which is essentially a semicircle. It is calculated based on the radius of the semicircle from which the Half Yin-Yang shape is made.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ A = \frac{\pi \times r^2}{2} \]

Where:

\( A \) — Area of Half Yin-Yang (m²)
\( \pi \) — Archimedes' constant (approximately 3.14159)
\( r \) — Radius of Half Yin-Yang (m)

Explanation: The formula calculates the area of a semicircle, which represents half of the Yin-Yang symbol's circular area.

3. Importance of Area Calculation

Details: Calculating the area of geometric shapes like the Half Yin-Yang is fundamental in mathematics, engineering, and design. It helps in understanding spatial properties and is essential for various practical applications.

4. Using the Calculator

Tips: Enter the radius of the Half Yin-Yang in meters. The value must be positive and valid.

5. Frequently Asked Questions (FAQ)

Q1: What is the Half Yin-Yang symbol?
A: The Half Yin-Yang is a semicircular shape derived from the traditional Yin-Yang symbol, representing one half of the whole.

Q2: Why is the area formula divided by 2?
A: Because the Half Yin-Yang is a semicircle, its area is half of the area of a full circle with the same radius.

Q3: Can I use this calculator for any semicircle?
A: Yes, this calculator can be used to find the area of any semicircle, not just the Half Yin-Yang.

Q4: What units should I use for the radius?
A: The radius should be in meters for the area to be in square meters. You can convert from other units if necessary.

Q5: Is the value of pi exact in the calculation?
A: The calculator uses the PHP constant M_PI, which is a close approximation of π (approximately 3.1415926535898).
