81π
Step-by-step explanation:
-The sum of central angles in a  circle add up to 360°.
-Let x be the area of the circle.
-Given the area of a 120° is 27π, the circles area can be calculated as:

Hence, the area of the circle is 81π
 
        
             
        
        
        
Answer:
3:6:9
Step-by-step explanation:
1/1+2+3 × 90 = 15
2/1+2+3 × 90 = 30
3/1+2+3 × 90 = 45
 
        
             
        
        
        
0.326= 326/1000
0.326= 163/500
0.326= 32.6%
