Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
6362 square kilometres.
314.16 square k,.
A circle with a radius of 0.9 km has an area of 2.54 square 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.
not possible to change an area unit into a length unit
km is a measurement of length, while a square km is a unit of area.
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.
if it is the radius of a circle then use the formula pie r2 so the ans is 22 X 2 X 1000 --------------- 7 that is 6285.71428
A kilometre is a unit of distance. A square kilometre is a unit of area. The two units are therefore incompatible.
Using 3.14 as Pi the area of circle is: 615.44
It is: pi*352 = 3848.451 square km to 3 decimal places
It is: 4*pi*64002 square km
