We need to find the area of sector. The formula for the area of sector is given by :

So, the area of a sector is equal to
.
Answer:
f(x)=3x
Step-by-step explanation:
This is pretty much slope-intercept form (y=mx+b) but b is not present in this situation. 3 projects per hour (3x).
f(x)=3x and its y-intercept will be (0,0).
