Answer:
85 units :)
Step-by-step explanation:
Since r = 9,
and the shaded sector is 120 (120 degrees is 1/3 of a full circle)
we can set up an equation.
1) pi *r^2 = area
2) Subsitute --> 3.14 x 9^2 = area
3) Solve --> ~256 units = area. This is the entire circle's area
4) Divide by 3. 256 /3 = ~85.
