Assuming the earth to be a sphere of radius 6370 km.If seventy five percent of the earth's surface is covered by water, then find how many square kilometres is area of the land.
3 answers
6370*0.75 or 6370/0.25
surface area of earth which is land
= (1/4)4πr^2
= π(6370)^2
= 127,476,091 km^2
=
= (1/4)4πr^2
= π(6370)^2
= 127,476,091 km^2
=
If 3/4 th part is covered by water , remaining part will pe area of land I.e. 1-3/4= 1/4 th part
Radius given=6370 ,
Area is sphere= 4πr^2
1/4(4*22/7*6370*6370)
After solving we will get the ans as -- 127527400 km^2
