The radius for Adam's place on the carousal is 6 ft, and Beth's is 3 ft.

here is what its asking

see the question marks?

- chaotic_butterflies

Uh kinda..

- anonymous

hold on let me redo it lol

- chaotic_butterflies

XD Okie, thank you!

the question marks are the distances, i chose 45 degrees as angle of rotation but you can choose any angle you want

- anonymous

so basically you can draw a circle like this

- anonymous

|dw:1433689565485:dw|

- anonymous

set radius of the circle to 3 for beth and 6 for adam

- anonymous

then find the arclength

- anonymous

arclength = angle*(pi/180)*radius for degrees

- anonymous

does this make sense?

- chaotic_butterflies

Wouldn't the angle of rotation be the same for Adam and Beth? I think I get what you're saying about arc length though, I understand that difference.

- anonymous

the angle of rotation will be the same for Adam and Beth yes, only the radius will be different, which will give a different arclength

- chaotic_butterflies

Ah

- anonymous

you get to choose the angle of rotation but it must be the same for both

- anonymous

because thats how the question is stated

- chaotic_butterflies

Did you just set it to 45 degrees in your drawings?

- anonymous

yes it set it to 45 degrees

- anonymous

in my drawings

- chaotic_butterflies

Beth:
arclength = 45*(3.14/180)*3
Is that how I should set it up?

- anonymous

yes if you are using a approximation of pi that looks correct

- chaotic_butterflies

I am, thanks! I'm going to finish working these out, will you check when I'm done?

- anonymous

post what you get and someone will take a look

- chaotic_butterflies

Okie

- chaotic_butterflies

Beth:
arclength = 45*(3.14/180)*3
arclength = 45*(0.017)*3
arclength = 2.295
Adam:
arclength = 45*(3.14/180)*6
arclength = 45*(0.017)*6
arclength = 4.59

- anonymous

well if you approximate the fraction 3.14/180 then those are correct, its probably best if you dont approximate but since you showed your work it might be ok, now you just need to say all that in sentences

- chaotic_butterflies

Bleh I don't like talking, but I'm sure I can manage..

- anonymous

haha i feel ya
