Answer:

D) 33,493.3 cm3

Step-by-step explanation:

We know that

The volume of the sphere (beach ball) is equal to

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

we have

[tex]r=20cm[/tex]

substitute

[tex]V=\frac{4}{3}\pi (20^{3} )=33,493.3 cm^{3}[/tex]

Answer:

D

Step-by-step explanation:

V=[tex]\frac{4}{3}[/tex] π [tex]r^{3}[/tex]

r=20 cm

V= [tex]\frac{4}{3}[/tex]π([tex]20^{3}[/tex])= 33,493.3 [tex]cm^{3}[/tex]
