Educational video for children to learn how to calculate the length of the circumference. The circumference is a curved, closed, flat line whose points are the same distance from the center. Owing to the fact that it's a line, its length is measured in feet, inches, miles or in other measuring units. The little ones will recap the parts of the circumference: center, radius and diameter, and will discover that to find the length of any circumference, we should multiply the radius by 2 by Pi (3.14). In the second part of the video, they'll be able to practice with several examples, ideal to understand the theory better.
