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

    @Icedragon50 Did peachpi's formula help you solve the problem?

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

    then i would have \[\frac{ 11 \pi}{ 12}\]

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

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

    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
