In the movie “Life of Pi”, he says the name Pi was more of a tribute to the irrational number which is the ratio of the circumference of a circle to its diameter. That's some interesting trivia, isn't it? Hungry for more? Did you know that if the diameter of a circle is 1 then the circumference is π? If you know the formula for solving circumference, then you can easily prove that. We have a lot more quizzes about circumference as well.

Can you guess the circumference of some round things like balls, coins, and even planets? How do you solve the circumference when the radius is given? Well, if you can answer those questions, then stop going in circles and try answering our quizzes. Where are you going? Circle back and get on with the quizzes!
