## Area of a Semicircle Calculator

Calculating the area of a semicircle can be a daunting task, especially if you don’t have the right formula or tools at your disposal. However, with the help of our Area of a Semicircle Calculator, you can easily and quickly determine the area of a semicircle without any hassle.

### What is a Semicircle?

A semicircle is a two-dimensional shape that is formed by cutting a circle in half along its diameter. As a result, a semicircle has one straight edge and one curved edge. The curved edge of a semicircle is known as the arc, while the straight edge is called the diameter.

### Formula for Calculating the Area of a Semicircle

The formula for calculating the area of a semicircle is:

Area = (π * r2) / 2

Where:

• Area is the total space inside the semicircle
• π (Pi) is a mathematical constant that represents the ratio of a circle’s circumference to its diameter (approximately equal to 3.14159)
• r is the radius of the semicircle, which is the distance from the center of the semicircle to the curved edge

### Example Calculations

Let’s walk through a couple of examples to demonstrate how to use the Area of a Semicircle Calculator:

Example 1: If the radius of a semicircle is 5 units, the area would be:

Area = (π * 52) / 2 = (3.14159 * 25) / 2 = 39.27 square units

Example 2: If the radius of a semicircle is 8 units, the area would be:

Area = (π * 82) / 2 = (3.14159 * 64) / 2 = 100.53 square units
