Answer:
x = -4
Step-by-step explanation:

Lets divide both the sides by -3.


Answer:
-4i = 4(cos 270 +i sin 270)
Step-by-step explanation:
We have a+ib = r(cosθ+isinθ)

Here a = 0 and b = -4
Substituting

-4i = 4(cos 270 +i sin 270)
Circumference = 2πr or πd
The formula for circumference is 2πr (2 times pi times the radius)
2r = d (The radius x 2 = the diameter), so the circumference also = πd (pi times the diameter)
