Find the length of a rope by which a cow must be tethered in order that it may be able to graze an area of 9856 sq meters.
clearly the cow will graze a circular field of area 9856 sq m and radius equal to the length of the rope.
Let the length of the rope be r mts
then, πr2=9856 ⇒ r2=9856×722=3136 ⇒r =56m
