We have the following:
1. Cylinder
The volume is:
[tex]V=\pi\cdot r^2\cdot h[/tex]
replacing
r = d/2 = 18/2 =9
h = 11
[tex]\begin{gathered} V=3.14\cdot9^2\cdot11 \\ V=2797.74 \end{gathered}[/tex]
The volume of cylinder is 2797.74 in^3
2. Prism
[tex]\begin{gathered} V=A_t\cdot H \\ A_t=\frac{b\cdot h}{2} \end{gathered}[/tex]
replacing
H = 74
b = 60
h = 91
[tex]\begin{gathered} V=\frac{60\cdot91}{2}\cdot74 \\ V=202020 \end{gathered}[/tex]
The volumen of right prism is 202020 ft^3
