Answer:
½pi or 0.5pi units²
Step-by-step explanation:
Area : angle
9pi : 2pi
x : pi/9
9pi/2pi = x/(pi/9)
4.5 × pi/9 = x
x = ½pi or 0.5pi units²
It’s corresponding angles
I know this is not an answer but, I love your handwriting!
It is soooo much neater than mine!

The inscribed angle is always half of the central angle.
So 60÷2=30
