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.

Square root (1 km^2) = 1 km.
1 square mile = 2.59 square km 1 square km = 0.39 square mile
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.
Answer: 1 mi² = 2.58998 km²
A circle with a radius of 126 km has a circumference of 791.68 km.
The surface area of Mars is approximately 144,798,500 square kilometers. The equatorial radius is about 3,396 km and the polar radius is 3,376 km.
The area of a circle can be calculated using the formula A = πr^2, where r is the radius. Given a radius of 45 km, the area would be approximately 6,366 square kilometers.
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
314.16 square k,.
A circle with a radius of 0.9 km has an area of 2.54 square km
It is: pi*352 = 3848.451 square km to 3 decimal places
Square root (1 km^2) = 1 km.
1 square km = 1 million square metres.
1 square mile = 2.59 square km 1 square km = 0.39 square mile
It is: 4*pi*64002 square km
1 square km of gravel
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.
