Answer:
Infinitely many solutions.
Step-by-step explanation:
5x-8y=-11
-10x+16y=22
---------------------
2(5x-8y)=2(-11)
-10x+16y=22
---------------------
10x-16y=-22
-10x+16y=22
---------------------
0+0=0

= 27
The formula to find the area of a sector is:
A = 
In this case:
Degree = 40
Radius = 8
^^^Plug these numbers into the formula given above
A = 
Solve
A =
π8²
A =
π64
A = 
A = 7.1111111π
When rounded:
7.1π is the area of the sector
