To find the circumference of a circle, we use the formula \( C = 2\pi r \). By substituting the radius r = 7 feet and using \( \pi \approx \frac{22}{7} \), we get \( C = 2 \times \frac{22}{7} \times 7 \). Simplifying, the 7 in the denominator and numerator cancel out, leading to \( C = 2 \times 22 = 44 \) feet. So the correct answer is 44 feet! 🎉 Now, here's a fun fact: did you know that ancient Egyptians created a version of the circle even before the term "circumference" existed? They used ropes and pegs to measure circular fields! Isn't that nifty? Also, if you're working on similar problems, remember that confusion often arises from using the diameter instead of the radius. Double-check which measurement you're starting with to avoid mistakes!
