To find the area of a sector of a circle use the next formula:

As the given circle has a outside angle 90º (it is not part of the sector of the circle) subtract the 90º from 360º (total angle of a circle) to find the angle of the sector:

Find the area of the sector with angle 270º:

Then, the approximate area of the given sector of a circle is 284.955 square inches
49 should be the correct answer.

Y = -3x + b
Plug in point
-4 = -3(3) + b
-4 = -9 + b, b = 5
Solution: y = -3x + 5
