Answer:

The volume of cylinder is:

49806.06 ft^3

Step-by-step explanation:

We are given a right circular cylinder with:

Height(h)=[tex]22\frac{1}{4}ft=\dfrac{89}{4}ft[/tex]

and a diameter is [tex]2\frac{2}{5}[/tex] times it's height.

i.e. [tex]\dfrac{12}{5}[/tex] times it height.

i.e. the diameter is given as:

[tex]\dfrac{12}{5}\times \dfrac{89}{4}=\dfrac{267}{5}ft.[/tex]

We know that the radius of cylinder is half the diameter.

Hence, radius(r) of cylinder is:

[tex]\dfrac{1}{2}\times \dfrac{267}{5}\\\\=\dfrac{267}{10}[/tex]

The volume(V) of cylinder is given by:

[tex]V=\pi r^2h[/tex]

[tex]V=3.14\times (\dfrac{267}{10})^2\times \dfrac{89}{4}\\\\V=\dfrac{19922423.94}{400}\\\\V=49806.06ft^3[/tex]

Hence, the volume of cylinder is:

49806.06 ft^3
