Answer:
147,558,601 sqkm
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
The surface area of earth covered with land has been 148,863,320.16 square kilometer.
Earth has been considered as the planet with life. It has been oval with 70.8 % being water. The remaining percent of earth covered with land has been 29.2%.
The surface area of earth (A) has been given as:
[tex]A=4\pi r^2[/tex]
Where, the radius of earth, [tex]r=6,371\;\rm km[/tex]
Substituting the values for the area of earth:
[tex]A=4\;\times\;3.14\;\times\;(6,371)^2\\A=509,805,890.96\;\rm km^2[/tex]
The surface area of earth has been 509,805,890.96 square kilometer.
The area covered with land has been 29.2%.
The area of earth's land ([tex]Area_{Land}[/tex]) has been given as:
[tex]Area_{Land}=509,805,890.96\;\times\;\dfrac{29.2}{100} \\Area_{Land}=509,805,890.96\;\times\;0.292\\Area_{Land}=148,863,320.16\;\rm km^2[/tex]
The surface area of earth covered with land has been 148,863,320.16 square kilometer.
