Answer:
inverse: y=sqrt(x)-9
domain: (0, +inf)
Step-by-step explanation:
y=(x+9)^2
sqrt(y)=x+9
x=sqrt(y)-9

Just incase u need the work. Its C.
Area of entire circle = (pi)(r^2) and r = d/2:
<span>A =(3.142)((3.2^2) = 32.17m^2 </span>
<span>Portion of circle in sector: </span>
<span>185degrees/360degrees = 0.514 </span>
<span>Multiply: </span>
<span>0.514(32.17m^2) = 16.5m^2 to 1 dp </span>
