area= 22/7 r²
3850(7/22)= r²
350(7/2)= r²
175(7) = r²
5(5)(7)(7) =r²

35 =r


and circumference =2(22/7)(35)
= 220cm answer

area of circle =22/7*r*r                                                                                                  3850=22/7*r*r
       3850*7/22=r*r
       
       77.471=r*r
       78=d[diameter

        circumference of circle =2*22/7 *d/2
                                             =44/7*78/2
                                              =44/7*39
                                              =2716/7=386.5m
