Let's learn about the number $\pi$! 🎉 1. Imagine you have a big round pizza 🍕. The number $\pi$ helps us understand things about circles, like this pizza. 2. $\pi$ is about 3.14, but it goes on forever without repeating! It's a special number for circles. 3. If you measure the distance around the pizza (the edge), that's called the circumference. 4. The diameter is the straight line across the pizza through the center. 5. $\pi$ is the ratio of the circumference to the diameter. That means: $$\pi = \frac{\text{circumference}}{\text{diameter}}$$ 6. So if the diameter of the pizza is 1 meter, the edge around is about 3.14 meters. Great job learning about $\pi$! Keep having fun with math! 🎯
