How to Find the Circumference of a Circle from Diameter | Geometry, Circles

How do we find the circumference of a circle from its diameter? We go over that process in today's math lesson!

All we need to remember to figure this out is the number pi! Pi is equal to the ratio of a circle's circumference to the circle's diameter, which is a constant ratio for all circles. Using this equality, we can easily solve for circumference in terms of diameter.

Remember pi is just a number, and it is approximately 3.14159.

I usually put my own music in the outros, but I love Vallow's music, and wanted to share it with those of you watching. Please check out all of his wonderful work.
