Hii.....
As 3850 cm square is the area of circle
then, 22/7×radius square = 3850 cm square
radius square=3850×7/22 cm square
radius square =175×7cm square
radius square =1225cm square
radius=square root of 1225cm square
radius=35cm
now,
circumference of circle is 2×22/7×radius
c=44/7×35
circumference is 220 cm.
HOPE IT WILL HELP YOU...
