BC²=AC²+AB²
      =8²+6²
      =64+36
       =100

BC=10cm

Area of biggest semicircle= 1/2 * 3.14 * r²
                                 =0.5*3.14*5*5
                                  =0.5*78.5
                                  =39.25 cm²

Area of 2nd Largest Semicircle = 0.5*3.14*r²
                                                     =0.5*3.14*3²
                                                   =0.5*3.14*9
                                                    =14.13 cm²

Area of smallest Semicircle = 0.5*3.14*r²
                                             =0.5*3.14*4²
                                             =0.5*3.14*16
                                             =25.12 cm²

Area of Triangle = 1/2 *b*h
                         = 0.5*6*8
                            =24 cm²

Area of shaded region = (24+25.12+14.13) - 39.25
                                    = 63.25-39.25
                                    =24 cm²
