Cool Science and Mathematical Experiment with Dad

We measured the diameter of a CD today. Then we started measuring the circumference of the CD and divided the two. We got an answer of 3.10. Then we started another object, a cup. Then we also measured the diameter and circumference and divided them. We got 3.15. We measured the diameter of the plate and multiplied by 3.15 and got the the circumference. Dad told me that pi has a number 3.14, and it goes on forever. And, I recognized that the numbers we got were close to the original pi. So if you wanted to know the circumference, measure the diameter and multiply it by 3.14 to get the circumference.

This is dad and me playing play station 2 (ps2). I want to make another video on heelying.

Hey,

I have been training Catey (my sister) to become a heely master! She has alot to learn but,
