volume of sphere with radius 6 m   =   \(\frac43*\pi*6^3=\frac43*\pi*216=288\pi \, \text{m}^3\)

 

volume of sphere with radius 3 m   =   \(\frac43*\pi*3^3=\frac43*\pi*27=36\pi \, \text{m}^3\)

 

 

\(\begin{array} \ 288π \, \text{m}^3 - 36π \, \text{m}^3 &=& 252π \, \text{m}^3 \\~\\ &\approx& 791.681 \, \text{m}^3 \end{array}\)
