The number pi may be hard to calculate but is super effective when you use it to calculate other things. For instance, if you round the number pi to just 9 digits after the decimal and use it to calculate earth’s circumference, the results would be amazingly accurate. For every 25,000 miles, the number pi will only err to 1/4th of an inch. If you love math, you will realize how amazing this actually is.
