Finding the Circumference of a Circle

This video tutorial explains how to find the circumference of a circle using the diameter or radius. It introduces the concept of circumference as the boundary of a circle and highlights the importance of the irrational number Pi (π) in these calculations. The video demonstrates that the diameter fits around the circumference π times, leading to the formula π times diameter. It also covers the alternative formula using the radius, which is half the diameter. The tutorial concludes with practice questions for viewers to apply their learning.
