Fast so confused
find the area of the shaded sector. leave your answer in terms of π.

area of a circle is pi x r^2

r = 9 ft so 9^2 = 81

so the full area in terms of PI is 81PI

 now the shaded area is 120 degrees ( one third of the full area)

120/360 = 1/3

 so divide 81 by 3 = 81/3 = 27

so shaded area is 27PI

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
