الهندسة والقياس: مساحة الدائرة

The video tutorial explains the concept of a circle, defining it as a closed curve with all points equidistant from a fixed center point. It covers the calculation of a circle's circumference using the formula involving pi and radius. The video also discusses circle sectors, using an analogy of cheese slices to illustrate the concept. Finally, it explains how to calculate the area of a circle by rearranging sectors into a parallelogram shape, leading to the formula involving pi and the square of the radius.
