Step-by-step explanation:
The radius of the circle is 24 units, then the area of the whole circle is

The shaded circle is limited by 45° angle, so its area is
of the area of the whole circle.
The area of the shaded circle is
Answer:
-3x+1y=-1
or
3x-1y=1
or
by multiplying with 1/3 the first equation we get
-1x+1/3y=-1/3
or from second equation
1x-1/3y=1/3
Step-by-step explanation:
y-y1=m(x-x1)
y1=-7
x1=-2
m=3
so
y-(-7)=3(x-(-2))
y+7=3(x+2)
y+7=3x+6
-3x+y=6-7
-3x+ 1y= -1
