Answer:
27
Step-by-step explanation:
The central angle of 120° is 1/3 of the entire circle of 360°, so the sector area is 1/3 of the circle area:
1/3×81 = 27
The sector area is 27.
Step-by-step explanation:
A=s*s
A=s^2
52=s^2
s=√52
s=7.2 one side of the square
s*4 to get the four sides
7.2*4=28.8 cm length of the first piece
40-28.8=11.2cm length of the second piece

Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
