Answer:
Area of the shaded part is 3.14 square unit.
Step-by-step explanation:
Area of the shaded part = Area of large semicircle - (Area of two small semi circles)
Area of large semicircle with center O = 
                                                                 = 
                                                                 = 2π
Area of semicircle with center O' = 
                                                       = 
Area of semicircle with center O" = 
Now substitute these values in the formula,
Area of shaded part = 
 
                                   = 
 
                                   = 3.14 square unit
Area of the shaded part is 3.14 square unit.
