Degrees are used to measure the arc of a circle. A full circle is 360 degrees, and a half circle 180. so 9 degrees would be 1/40th of a complete circle.

If it's a regular 9 sided polygon then each interior angle will measure 140 degrees.
It is a 9 sided nonagon and its 9 interior angles add up to 1260 degrees
I assume you want the area of the sector with angle 120o and radius 9 cm: 120o is 120/360 = 1/3 of a full circle. ⇒ area of sector is 1/3 area of full circle ⇒ area_of_sector = 1/3 x π x radius2 = 1/3 x π x (9 cm)2 = 27π cm2 ≈ 84.82 cm2
2pi/9 radians or 40 degrees
4/9*pi*r where r is the radius of the circle.

suck this dudck.
Radius is 9 so area of complete circle (360o) is 81 x 3.14 ie 254.34. Angle of sector is therefore 360 x 169.56/254.34 which is 240o
If the angle at the centre is 60° then the sector occupies 1/6 of the circle as 60/360 = 1/6. The area of a circle = πr² The area of the sector = 1/6.π3² = 9/6.π = 4.712 square units.
Each exterior angle will measure 9 degrees
400 exterior angle = 360/9 = 400
