Hello i don't get this answer at all if someone does please answer to this question

D

Step-by-step explanation:

To find the average, add up all of the values and then divide by the number of values.

So first, add (-5) + (-4) + (-7) + (-2) + (2) + (5)

You get -11. Then, divide -11 by the number of values (6)

-11/6 is about -1.83, which rounds to -2

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)

(-5,-28)
