Answer:
The answer is 2pi
Step-by-step explanation:
To find the area of a cirlce, use the equation ( pi * r^2 ) so for a semi circle, which is half, simply divide that by 2. Plug in 2 for radius and you get 4pi/2 which simplifies to 2pi.

Answer:
(-4,-3)
Step-by-step explanation:
-3x+3y = 3
2x-y =-5
Divide the first equation by 3
-x+y =1
Add this to the second equation
-x+y=1
2x-y =-5
---------------
x = -4
Now we need to find y
-x+y =1
-(-4) +y = 1
4+y = 1
Subtract 4 from each side
4-4 +y = 1-4
y =-3
(-4,-3)
