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)
The area of a circle with a radius of 10 km is πr^2, where r is the radius. In this case, the area would be approximately 314.16 square kilometers.
A circle with a radius of 0.9 km has an area of 2.54 square km
Square root (1 km^2) = 1 km.
It is: pi*352 = 3848.451 square km to 3 decimal places
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.
