Volume of the composite solid is the sum of the volume of the cylinder and volume of the hemisphere.

The radius of the cylinder is 12/2=6 cm

Height of the cylinder is 26 cm

Volume of the cylinder is given by


V_1=\pi r^2h

Hence the volume is given by


\begin{gathered} V_1=3.14*6*6*26 \\ =2939.04 \end{gathered}

Now the volume of the hemisphere is


V_2=(2)/(3)\pir^3

Hence the volume of the hemisphere is


\begin{gathered} V_2=(2)/(3)*3.14*6*6*6 \\ =452.16 \end{gathered}

And the total volumeis


V=2939.04+452.16=3391.2
