First, determine the area of the whole circle by the equation, A = πr². Substituting,
                             A = π(6²) = 36π
Then, multiply this value with the ratio of the given angle to the whole revolution,
                            A(sector) = 36π x (120° / 360°)
The area of the sector is therefore 12π units².
        
             
        
        
        
Answer:
The expression is 2k + 4.
Step-by-step explanation:
You have to collect like-terms :
(8k + 9) - (6k + 5)
= 8k + 9 - 6k - 5
= 2k + 4
