To find the circumference of the circle, you can use the formula \( C = 2\pi r \). With a radius of 9 yards, just plug in the value: \( C = 2\pi(9) \), which gives you approximately 56.55 yards when you use 3.14 for \(\pi\). So, your circle's circumference is about 56.55 yards. Now, imagine drawing this circle in a park while envisioning it as the perfect running track! With that kind of circumference, you could sprint a lovely lap while enjoying nature and the fresh air. Plus, you might win a race against your friends with little effort - distance matters after all!
