If youknow the diameter of the circle, then
Circumference = (π) x (Diameter).
If youknow the radius of the circle, then
Circumference = (π/2) x(radius).
If you know the area of the circle, then
Circumference= 2 √ (π A) .
I think the answer should be B.
Answer:
I think its 1/3/ and 4. But I dont know tho. just make sure with other.

Step-by-step explanation:
5x-4=-3-x
5x+x=4+(-3)
6x=1
x=1/6
Answer:
Step-by-step explanation:
Given that angle A is in IV quadrant
So A/2 would be in II quadrant.
sin A = -1/3
cos A = 
(cos A is positive since in IV quadrant)
Using this we can find cos A/2
