Answer Posted / Vikash Singh
The cow can graze an area equal to the circumference of the circle described by the endpoints of the rope, since the cow can reach as far as the ends of the rope. The radius of the circle is 5 meters (half the length of the rope). Therefore, the area of land the cow can graze is pi * r^2 = pi * 5^2 = 25pi square meters.
