An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2.

Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.

A circle with a radius of 5 units has an area of 78.54 square units.

First of all, there is no reason to suppose that the area is circular as opposed to rectangular or triangular or some other simple or complicated shape. If, on the basis that the question asks for the radius, you assume that it is a rectangle, then the radius is 0.564 km = 564 metres.

It is 78.5 square units.

It is: 25*pi square m

Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
