Answer:
[tex]V=382\ cm^3[/tex]
Step-by-step explanation:
The radius of a rubber ball, r = 4.5 cm
We need to find the volume of this rubber ball.
The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
Put r = 4.5 cm in the above formula
[tex]V=\dfrac{4}{3}\pi \times (4.5)^3\\\\V=381.70\ cm^3\\\\\text{or}\\\\V=382\ cm^3[/tex]
So, the volume of this sphere ball is [tex]382\ cm^3[/tex].
