Step-by-step explanation:

(1) The radius of sphere is 4.5 units.

The volume of volume of sphere is given by :

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

[tex]\pi=3.14\ , r=4.5[/tex]

So,

[tex]V=\dfrac{4}{3}\times 3.14\times (4.5)^3[/tex]

Option C is correct.

(2) If we solve the plugged values, then we get :

[tex]V=\dfrac{4}{3}\times 3.14\times (4.5)^3[/tex]

[tex]V=381.5\ \text{units}^3[/tex]

Option C is correct.
