the end of 10 years.
A) $24,005.10
C) $5,860.13
B) $5,866.93
D) $8,072.64

Step-by-step explanation:

Using formula

Substitute values

Option A is correct

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)
