Math trivia question of the day... (intended for you to laugh at how little we all know about math) Q. Say you have a rope long enough to reach all the way around the equator: 24,901 miles. Say someone asks you to elevate that rope another foot higher off the ground. How much extra rope would you need (all numbers are rounded)? (answer below) A) 6.28 feet B) 249.01 miles C) 24,901 miles D) 49,802 miles E) 79,189 miles . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Answer: A. No matter the circumference, the answer is always 2 pi. It's easier to visualize the earth as a square. If you separate the four lines that make up the square and move each one a foot away from the one parallel to it, you just need enough rope to connect the corners back together-- another two feet for each corner, or 8 feet total. A circle fits inside a square, so 6.28 makes sense anyhow. This words regardless of the original size of the circle (or square).
