Answer:
Area of the shaded region = 23.33 in²
Step-by-step explanation:
Area of a sector = 
Where θ = Central angle subtended by an arc
r = radius of the circle
Area of the sector BCD = 
                                        = 52.36 in²
Area of equilateral triangle BCD = 
                                                       = 
                                                       =  in²
 in²
                                                       = 43.30 in²
Area of the shaded portion in ΔBCD = 52.36 - 43.3
                                                              = 9.06 in²
Area of sector CAD = 
                                  = 39.27 in²
Area of right triangle CAD = 
                                             = 
                                             =  
 
                                             = 25 in²
Area of the shaded part in the ΔACD = 39.27 - 25
                                                                          = 14.27 in²
Area of the shaded part of the figure = 9.06 + 14.27
                                                                 = 23.33 in²
 
        
             
        
        
        
Step-by-step explanation:
25 is the answer . hope it helps
 
        
             
        
        
        
Literal equation:
we know that
literal equation is equation of more one variable 
for example: 
And we can solve such equations only if we are given two such equation 
because it has two variables
One variable equation:
such equation has single variables
for example:

we don't need any other equation 
we can solve for variables from single equation itself 
because it has only one variable that is x
