Ok so this lvl i dont really get it, i know what i have to do but dont know how to code it

Any help?

this is the code

```
# Defeat Yetis.
# The chosen one can stun yetis with a Shout.
chosen = hero.findFriends()[0]
# The power of the Shout is equal to the area of a circle.
radius = chosen.distanceTo(chosen.findNearestEnemy())
# The area of a circle can be calculated with the formula:
area = radius * radius * Math.PI
# Tell the area to the chosen one.
# Don't just stand there! Fight!
```
