Calculating the area of half of a circle is based on the concept of sectors and the properties of circles. A circle is divided into 360°, and a half-circle or a semicircle is exactly half of that, spanning 180°. The formula to calculate the area of a full circle is A = πr^2, where r is the radius. To find the area of a half-circle, we need to find the area of a full circle and divide it by two.
