Answer:
81 π
Step-by-step explanation:
The total central angle for a circle is 360 degrees.
In the question the sector with angle 120 degrees has area 27π.
So the circle can be considered as a combination of 3 sectors having angle 120 degrees each. Refer to the figure below.
Thus area of the circle will be three times of the area of the sector.
Area = 3 × 27π = 81π
