Step-by-step explanation:

Let's model the beach ball as a sphere, whose circumference is and is calculated by:

(1)

From there we can find the radius :

(2)

(3)

Now, the volume of a sphere is given by:

(4)

Substituting (3) in (4):

(5)

Finally:

This is the volume of the beach ball.

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)
