arc length = r*π*angle in degrees/180

hmm

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

anonymous · Answer

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

anonymous · Answer

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

jtvatsim · Answer

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

:O

anonymous · Answer

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

jtvatsim · Answer

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

anonymous · Answer

okie :P

jtvatsim · Answer

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

anonymous · Answer

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

jtvatsim · Answer

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

anonymous · Answer

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

jtvatsim · Answer

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