Question

Earth has a diameter of about 2292 leagues long. What is the total surface area of earth? Rounded to the nearest whole number.

Answer 1

Answer: 16,503,616 leagues²

Explanation:

Assume that the Earth is a sphere. Then, you need to use the formula for calculate the surface area of a sphere:

`SA=4\pi r^2`

Where r is the radius.

Divide the diameter by 2 to calculate the radius of the Earth:

`r=(2,292\ leagues)/(2)\\r=1,146\ leagues`

Substituting values into the formula
`SA=4\pi r^2`, you get that the total surface of the Earth to the nearest whole number is:

`SA=4\pi (1,146\ leagues)^2=16,503,616\ leagues^2`
