Answer:
4 cm
Step-by-step explanation:
Perimeter = 18cm
θ = 2.5 radian 
s = rθ, s = Arc length 
Perimeter of Sector, P = arc length, s + 2r 
Perimeter = rθ + 2r 
r = Radius 
18cm = r(2.5) + 2r 
18cm = 2.5r + 2r 
18cm = 4.5r 
r = 18 /4.5
r = 4
 
        
             
        
        
        
Answer:22/

 ≅ 2.4444444
Step-by-step explanation:
Add: -19 + 9 = -10
Absolute value: abs(the result of step No. 1) = abs(-10) = 10
Divide: the result of step No. 2 / 3 = 10 / 3 = 3.3333333333333 = 10/
3
Subtract: 14 - 22 = -8
Absolute value: abs(the result of step No. 4) = abs(-8) = 8
Divide: the result of step No. 5 / 9 = 8 / 9 = 0.88888888888889 = 8/
9
Subtract: the result of step No. 3 - the result of step No. 6 = 10/
3
 - 8/
9
 = 10 · 3/
