The highlighted sector is exactly 3/4 of the circle area, because 
is 3/4 of 
which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be 
squared cm.
The remaining sector, of course, is 
squared cm.
Equation of line h is y=-2x-1
Slope is -2 (because it’s parallel)
so you have y=-2x+a
now you have to plug in the points it needs to pass through -9=-2(4)+a
do -2(4)
isolate a so then you would add the -8 to the other side
do the math of -9-(-8)
that’s how you get y=-2x-1
Answer:
