Best ResponseYou've already chosen the best response.1oh ok, same formula...but now we have to move things around because we want the angle not the arc \[arc = r* \frac{\text{\angle}}{180} \pi = (\frac{\pi r}{180}) \text{\angle}\] by multiplying by reciprocal we can get "angle" by itself \[\text{\angle} = (\frac{180}{\pi r})*arc\]

Best ResponseYou've already chosen the best response.1now try plugging in arc of 6pi, and r of 8 \[Angle = \frac{180}{8\pi}* 6\pi\]

Best ResponseYou've already chosen the best response.0Ok so it's giving me diameter... what's the formula then?

Best ResponseYou've already chosen the best response.0Cause I tried just pi times the diameter and it wasn't right...

Best ResponseYou've already chosen the best response.1right pi * diameter will give you circumference you need to know how to convert diameter to radius > r = d/2 easy radius is half the diameter \[A = \pi r^2 = \pi (\frac{d}{2})^2\]

Best ResponseYou've already chosen the best response.1oh well thats because they want area of blue part, NOT the circle :) what did you get for circle?
