It covers approximately a 70% of the Earth's surface, formed by a combination of Hydrogen and Oxygen atoms and with an average area of 361 times ten to the power of six km2. (361x 10**6 km2)
The surface area is 314.2
The formula of the sphere to find surface area is A = 4•3.14•r^2 , substitute 5 for r, then multiply 5^2, after you get that product then multiply it by 3.14/pi. Once you get that product, multiply that by 4 and you get the final product. Then round to the nearest tenth, which is how you get 314.2
5.25 or as a fraction 21/4 which is 5 1/4
