Question:
What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the values of radius and central angle are not given.
However, I'll answer the question using the attached figure.
From the attached figure, the radius is 3 unit and the central angle is 120 degrees
The area of a sector is calculated as thus;

Where
represents the central angle and r represents the radius
By substituting
and r = 3
becomes



square units
Solving further to leave answer as a decimal; we have to substitute 3.14 for 
So,
becomes

square units
Hence, the area of the sector in the attached figure is
or 9.42 square units
