Answer:
[tex]v=678.24 ~ ft^3[/tex]
Step-by-step explanation:
[tex]v=\frac{\pi r^2h}{3}[/tex]
[tex]height~ of Figure~ A[/tex]
[tex]v=25.12 , r=2[/tex]
[tex]25.12=\frac{\pi 2^2h}{3}[/tex]
[tex]3(25.12)=\pi4h[/tex]
[tex]\frac{75.36}{4\pi } =\frac{4\pi h}{4\pi }[/tex]
[tex]h=\frac{75.36}{12.56}[/tex]
[tex]h=6[/tex]
[tex]volume ~ of ~B:-[/tex]
[tex]r=6, h=18[/tex]
[tex]v=\frac{\pi r^2h}{3}[/tex]
[tex]=3.14(6^2)(18)/3[/tex]
[tex]=3.14(36)(18)/3[/tex]
[tex]= 2.034.72/3[/tex]
[tex]v=678.24~ ft^3[/tex]
