π What Is the Area of a Semicircle?
A semicircle is half of a full circle. Therefore, its area is exactly half the area of a circle with the same radius. The area of a semicircle is measured in square units (like cmΒ², mΒ², inΒ², etc.) and is widely used in architecture, landscaping, and mathematics.
π Area of a Semicircle Formula
Where:
- Ο (Pi) β 3.1416
- r is the radius of the semicircle
Alternative formula (using diameter d):
βοΈ Example Calculation:
If the radius of a semicircle is 7 cm:
β So, the area of the semicircle is approximately 76.97 square centimeters
