Desert Shores has an elevation of -61.2 meters. Shatt al Gharsah has an elevation of -17.1 meters. Note that both places have negative elevations because they are below sea level.
Which one of the following inequalities correctly compares the elevations?

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the correct answer is x/3+10≥32

hope this !
