You may already know all about the mathematical constant pi (π) and how it can be used to calculate things like the circumference of a circle or the volume of a sphere. But did you know pi is also used all the time by NASA scientists and engineers to explore other planets?

In this challenge, you can solve some of the same problems NASA scientists and engineeers do using pi!
