if your given the radius 6 meters and area of sector of circle 8 squared meters how do you find the central angle?

Question

anonymous · Answer

sector area is a/360 * pi r^2

anonymous · Answer

the formula is central angle/2pi = A /pir^2.

anonymous · Answer

so what he said above me.

anonymous · Answer

you're *

anonymous · Answer

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.

anonymous · Answer

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?

anonymous · Answer

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
