Answer:
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 :
V=\dfrac{4}{3}\pi r^3V=34πr3
Put r = 4.5 cm in the above formula
\begin{gathered}V=\dfrac{4}{3}\pi \times (4.5)^3\\\\V=381.70\ cm^3\\\\\text{or}\\\\V=382\ cm^3\end{gathered}V=34π×(4.5)3V=381.70 cm3orV=382 cm3
So, the volume of this sphere ball is 382\ cm^3382 cm3 .
