The table shows how many miles Sally drove, y, in x hours. What is the constant rate of change in the number of miles Sally drove?

(X)73.2miles=the change in the constant rate of miles.

the number of miles times 73.2 equals the constant change of miles.

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)

if you mean

then it's c. 8, -7/3

but if you mean

then it is
