Answer: circumference = 2Πr²
Where r= 3
Π=3.14
Therefore Circumference = 2×3.14× 3²
= 2×28.26
Circumference=56.52
Formula:
Subtitute in 3 for r.
Solve and the answer is 28.26
17 divided by 1/3= <span>5.66666666667 which rounded, is approximately 6.

I think it's either A or D. but I'm leaning towards A so try that one
Could we get a little bit more in detail
So We Know That tan(x) Equals

We Can Use Logic, We Know That Anything That Makes The Denominator 0, Will Not Work, So We Need To Know What Makes Sin(x) equal to 0 and Cos(x) equal to 1 or -1 BUT NOT 0


We Didn't Want Cosine To equal Zero Because Then We Get

THE ANSWER IS C : -360°,-180°,0°,180°,360°
