€ = 7/9
7/9÷2 = .389
C = 2pi•r = 2•pi•18 = 36pi
WV = 7/9 (36pi) = .389 (36)pi = 14pi
So C) 14pi is the answer
        
             
        
        
        
Answer:
an = 6 +5(n-1)
an = 1 +5n
Step-by-step explanation:
The equation for an arithmetic term is
an =a1 +d(n-1)
 where a1 is the 1st term and d is the common difference
an = 6 +5(n-1)
We can distribute the 5
an = 6+5n-5
an = 1 +5n
