Edge of triangle=2 radius
area of triangle=17320.5 cm^2
therefore area of triangle=3^(1/2)/4*a^2
                  17320.5cm^2=3^(1/2)/4*a^2
173205/10*4/3^(1/2)cm^2=a^2
                                      a=194.14cm
                                      a=2r
                      194.14 cm=2r
                                      r=97.07cm
area of three sectors=3*60/360*22/7*97.07*97.07 cm^2
                                  =14806.92 cm^2
area of triangle not included in the circles=area of triangle -area of three sectors
                            =(17320.5-14806.9)cm^2
                            2513.6 cm^2
