Answer:
x = 13
Step-by-step explanation:
The sum of the exterior angles of a 4 sided polygon is 360
139+ 6x+9x+2x = 360
Combine like terms
139+17x=360
Subtract 139 from each side
17x = 360-139
17x = 221
Divide each side by 17
17x/17 = 221/17
x = 13
C = pi * r ^squared
r = is radius
square the radius, multiple by r
or
2 x pi x r
We have,
Introduce variable 
such that 
The sum 
is therefore 
So,
