Based on the provided reference (a YouTube video titled "Pi for Kids"), a "pi kid" is not formally defined. However, we can infer that it refers to a resource or concept aimed at explaining the mathematical constant pi in a way that is understandable and engaging for children.
The video aims to introduce children to pi by:
- Explaining the relationship between a circle's circumference and diameter.
- Demonstrating that dividing a circle's circumference by its diameter always results in pi (approximately 3.14).
Therefore, in the context of the video and its title, a "pi kid" is about making pi accessible to kids. It is not a formal term but rather an implied subject or audience.
