Alana set her watch 5 seconds behind, and it falls behind another 2 seconds everyday. How far back is Alana's if she last set 12 days ago?

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)

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

if you was gonna solve for a, a is a   < -12

b
