## anonymous one year ago A Ferris wheel has a radius of 80 feet. Two particular cars are located such that the central angle between them is 165º. To the nearest tenth, what is the length of the intercepted arc between those two cars on the Ferris wheel? HELP

arc length = r*π*angle in degrees/180

hmm

well i think first i have to convert 165 degrees to radians form

13. anonymous

then i would have $\frac{ 11 \pi}{ 12}$

14. jtvatsim

That is correct! Peachpi's formula already is doing this for you.

:O

16. anonymous

oh when i plug it into peach pi's formula i get 230.4 right?

17. jtvatsim

Let me check... I'm not as fast with a calculator. :)

18. anonymous

okie :P

19. jtvatsim

Yes, and that is the correct answer to the problem. Of course, don't forget units. :)

YAY so 230.4 feet is the answer thanks so much :D

21. jtvatsim

You're welcome! What you did with 11pi/12 was the pi*angle in degrees/180 part of peachpi's formula. Nice work.

sowwy but i think since peachpi gave the ormula he should get the medal :P

23. jtvatsim

I agree, and gave peachpi a medal as well. :)
