# 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?

May 22, 2017

The surface area of Mercury is $19477 {\text{miles}}^{2}$

#### Explanation:

$S A = 4 \pi {r}^{2}$

$r = 1550$

$S A = 4 \pi {1550}^{2}$

$S A = 12.566 \times {1550}^{2}$

$S A = 19477.88 {\text{mi}}^{2}$
