a) 15/7

step-by-step explanation:

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)

answer is  

c.

36

step-by-step explanation:

5 + 8 +7 + 4 + 0 +1 = 25
