Answer:
Step-by-step explanation:
9L/4days = 2L/1day, which is the unit rate.  
  
Over the course of 4 days: (2L/day)(4 days) = 8 Liters
 
        
             
        
        
        
The area of a circle is pi times the radius squared
        
                    
             
        
        
        
96°. 
Since sides AB and AC ane equal, that means that angle B is equal to angle C. The measurement of all the angles of a triangle always equals 180°, so if you add angles B and C, you should get 84° and then you should be able to find angle A. Subtract 84° from 180° and you should get 96°.
