Question

A plant its radius is approximately 4012 miles about 2/3 of the planet surface is covered by water enter an estimate for the land area on the planet round the answer to the nearest million

Answer 1

The area of land is 0.067 million squared miles.

Explanation:

The shape of a planet is sphere.

The surface area of a sphere is
`4\pi r^2`.

Given that, the radius of the planet is approximately 4012 miles.

Total surface area of the planet is
`=4 \pi (4012)^2`

= 202,351,5224.6 squared miles

=0.202 million squared miles

`\frac 23` of the plane surface is covered by water.

`(1-\frac23)=\frac13` of the plane surface is covered by land.

The area of land is =
`\frac13 * 0.202`

= 0.067 million squared miles
