How much air would be needed to fill a bouncy ball with a radius of 9 cm?

A. 108π cm3

B. 486π cm3

C. 972π cm3

D. 3052π cm3

The volume of a sphere = (4/3)r^3

r = radius

In our problem,

r = 9 cm

To find the volume of this sphere, plug our radius into the volume equation.

V = (4/3)(9)^3 = 972cm^3

The correct answer is C

the first one

Step-by-step explanation:

if you add the numbers together you get 13 but it can't be a negative so you turn it into a fraction so it becomes positive.

Hope that helps
