The answer to this question is -21
The central angle corresponding to AOB is half of the 8pi/9 radians mentioned, meaning that the central angle of AOB is 4pi/9.
Converting that to degrees:
4pi/9 180 degrees
-------- * -------------------- = 80 degrees.
1 pi
Domain is all real numbers.
Range is all real numbers geater than 0
3/10 that's what the answer is
If you turn the ratio 1:3 into a fraction it would be 1 over 3 I hope this helps
