Given data
*The given radius is r = 39.4 ft
The expression for the volume of the hemisphere is given as
[tex]V=\frac{2}{3}\pi r^3[/tex]Substitute the values in the above expression as
[tex]\begin{gathered} V=\frac{2}{3}\times3.14\times(39.4)^3 \\ =128034.51 \end{gathered}[/tex]Thus, the volume of the hemisphere is V = 128034.51
