Answer:
The area of land is 0.067 million squared miles.
Step-by-step explanation:
The shape of a planet is sphere.
The surface area of a sphere is [tex]4\pi r^2[/tex].
Given that, the radius of the planet is approximately 4012 miles.
Total surface area of the planet is [tex]=4 \pi (4012)^2[/tex]
= 202,351,5224.6 squared miles
=0.202 million squared miles
[tex]\frac 23[/tex] of the plane surface is covered by water.
[tex](1-\frac23)=\frac13[/tex] of the plane surface is covered by land.
The area of land is =[tex]\frac13 \times 0.202[/tex]
= 0.067 million squared miles
