Here's the question you clicked on:

if your given the radius 6 meters and area of sector of circle 8 squared meters how do you find the central angle?
sector area is a/360 * pi r^2
the formula is central angle/2pi = A /pir^2.
so what he said above me.
8 = a/360 36pi 113a = 8 a = 14.125/360 so is the measure 14.125 degrees. i've no idea. lol this is weird.
a/2pi = 8/36pi a/pi = 4/36pi 12.56 = 113a a = 9 according to marcs formula so yeah :)
say thanks to my cal teacher haha just came from the unit circle :) but your definition looked right you were just mising the area of the circle i think?
Yep, well i'm only in geometry and we did stuff like this. but it's different working backwards.
Id say more here but this isnt a conversation area :) haha
