Question

The formula for the surface area of a sphere is `SA = 4pir^2` If the radius of Mercury is 1550 miles, what is its surface area to the nearest square mile?

Answer 1

The surface area of Mercury is `19477"miles"^2`

Explanation:

`SA = 4 pi r^2`

`r = 1550`

`SA = 4 pi 1550^2`

`SA = 12.566 xx 1550^2`

`SA = 19477.88"mi"^2`
