Acute angle bc its the smallest angle
Answer:
radius 2 meters
Step-by-step explanation:
Take the circumference formula 
Divide both sides by pi ÷ 3.14 ÷3.14
4=d
Divide by 2 to find radius 4 divided by 2 is 2
Answer:
If
we get
which is true. so we have a first set of solutions given by
;
Else, if
we can divide both sides by it and we get

Which gives us a second set of solutions given by
;
We can group all solutions (doesn't matter, but it's more elegant!) by writing
