Area of a sphere is (4) pi x r2. Since the earth's radius is about 6400 km then
Area = (4) x pi x (64002) = 515,000,000 = 5.15 x 108 square kilometers
Uranus has the surface area of 15.91 Earths. It has the volume of 63.086 Earths. It has the mass of 14.536 Earths. Its diameter is 4.007 times that of Earth. See the related link for more information.

Yes. There are ways to do that, but it depends on what you wish to change the surface area of. Changing the surface area of something like, say, a shotput is difficult, but changing the surface area of a balloon can be accomplished by merely blowing it up (more) or deflating it.
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
The most well developed scientific area at the beginning of the academic-discipline movement was
It is approx 6.09*10^18 square metres.
It is approx 6.1×10^12 square km.

The diameter of a grain of sand is 0.0025. In scientific notation, this is written as 2.5 x 10^-3
Surface area is 16650000 km2 or about 0.033 Earths
