To find the distance around the circle, you must find the diameter, which is two times the radius. Then you multiply the length of the diameter by Pi. (Pi is a constant roughly equal to 3.14).

First, it is not an approximation but the formula for the exact value of the volume. Second, pi and e are quite different numbers.
It is approximated that 70.8% of all of Earth is covered in water, including lakes and other isolated bodies.
Teaspoons are often approximated to 5 grams so roughly 5.
This theorem tells, roughly, that any mathematical system can be approximated by fuzzy logic. Hopefully this page http://sipi.usc.edu/~kosko/ helps more.
It roughly follows the meridian of 180° longitude.
Greenwich
Using your value of a, the answer is 4x3x7x7 square metres. More accurate to use the correct value of a, which is pi (ie nearer to 3.142) 588.2 m2
The IDL roughly follows the meridian of 180° longitude.
Water, roughly 70%.
The number represented by 2^4570 is 1376 digits long. It can be roughly approximated as 5.0942 E1375. In comparison, this is 1.170553580436311 E1358 times the number of seconds since the universe began.
