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



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

 square units
 square units
Hence, the area of the sector in the attached figure is  or 9.42 square units
 or 9.42 square units
 
        
             
        
        
        
The radius of the sector of the circle with the given area is: B. 3.
<h3>What is the Area of a Sector?</h3>
Area of sector of a circle = ∅/360 × πr².
Given the following:
Area of sector = 9/8 π cm².
∅ = 45 degrees
Plug in the values into the formula
9/8π = 45/360 × πr²
1.125 = 0.125 × r²
1.125/0.125 = r²
9 =  r²
r = 3 cm
