Circles And Circular Figures: Learn about the circumference of a circle

This video tutorial introduces circles, focusing on their properties such as diameter, radius, and circumference. It explains how the diameter is the distance across a circle through its center, while the radius is half of that distance. The concept of circumference is likened to the perimeter of a circle, calculated using Pi, a special mathematical constant. The tutorial emphasizes the importance of Pi in various mathematical contexts, including geometry and beyond.
