its kind of loud to me. I need to move to the country.

pi x the square of the radius (whatever amount that is)

Sorry

lol your right thats a circle not a sphere. *facepalm*

yeah its on the third shelf between the volumes ear and earthworm thank you for asking

The pic what you have in your ID, Can you define it's area?

errr by the seaside

Tell its area?

Just define what it means? It's the amount of space it takes up. (1.1 x10^21 m^3)

Just use your mind and am sure you will get..........

4/3 pi x the cube of the radius.

Would you please define the whole theory?

It's more of a formula than a theory. You measure (or in this case, google) the radius of the earth, then multiply it by itself twice. Divide pi by 3 then multiply by 4. Multiply the result of both of these actions and you'll have your answer.

You just approaching to ans. but can't touching it.....
Sorry

The difficulty you're having is that you have definitions confused with explanations, and proven formulas confused with theory. My answer is fine. Your question is faulty. Sorry, but it's true.

269 593 366 780 586 km3 (square kilometres) using chipsters correct formula (wish the calc had let me paste that.) starting radius 40 075 km
