Answer 4

sorry i went afk for a while >.< i know it just trying to write out an explanation >.<

Answer 5

?

Answer 6

s = arc length
The equation is s = \({\theta}\)r where it becomes \({\theta}\)=s/r.
If \({\theta}\) = 1 radians then s/r = 1.

So A is an answer.

Answer 7

I think C is too but I dont know >.<

Answer 8

Hmm ya A looks good.

C. If the measure of theta=1, then...
\(\large\rm s=r\cdot\theta\qquad\to\qquad s=r\)
then the arc length is r, ya?

So clearly C is false.

Answer 9

I skipped a step in the middle,
r*theta gets replaced by r*1 which is simply r.

Answer 10

D. If theta is 60 degrees, then...
\[\large\rm s=r\cdot \theta\qquad\to\qquad s=r\cdot \frac{60\cdot \pi}{180}\]I guess we would need to convert to radians, ya?
Are you familiar with that process? :o
\[\large\rm s=\frac{\pi}{3}\cdot r\]
So then the arclength is equal to pi/3*r
not just r

Do D is false as well.

What do you think? Too confusing? :O

Answer 11

*head slowly breaking*
So B is also false, right?
