Explanation:
The earth is spherical in shape;
area of sphere = 4πr²
if 70.8% is covered by water then 100-70.8 will be land,
= 29.2%
area occupied by land = (29.2/100) * 4πr²
= 0.292*4*3.142*(6371)²
=147,558,601 sqkm

Answer:
9.31 g = 0.00931 kg
Explanation:
We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.
The relation between kilogram and gram is as follows :
1 kg = 1000 g
or
1 g = 0.001 kg
If we change 9.31 gram to kg, we get :
9.31 g = (9.31 × 0.001) kg
or
Hence, 9.31 g is the same mass as 0.00931 kg.
