This video illustrates the concept of pi as a constant. It teaches: Circumference is the distance around a circular object or shape. Diameter is the length of a straight line from one end of a circle to the other end, passing through the centre. It divides the circle into two equal halves. Radius is the length of a line from the centre of a circle to any point on its circumference. It is half the diameter of a circle. When the circumference (C) of any circle is divided by its diameter (d), the answer is always the same number (constant) called pi. The symbol for pi is π.
