Answer:
2,777.8 km or 1,729.2 mi
Step-by-step explanation:
first think about how many degrees would you travel if you wanted to do a whole circunference always going south: it would take 360 degress to complete a circunference.
Then you can use a rule of three to find the answer:
If the whole circunference is 40,000km and in degrees is 360, then how much 25 degrees would be?


Answer:
Radians
Step-by-step explanation:
If you use degrees, you have to put an annoying 2π/360 every time you try to simplify. This is why in calculus, we work with radians for all functions of derivatives, since its much easier to work with, and you dont have to write that annoying constant.
