3r + 3s = 3(r + s) answer
So if we have the number after the 36% increase in population, we would want to subtract that 36% from 51000.
36% of 51000 can be found by multiplying 51000 by 0.36 (0.36 is the decimal equivalent of 36%)
51000 x .36 = 18360
So you simply subtract 18360 from 51000, which is 32,640.
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
