Answer:
2.39 feet
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
where
r is the radius of the base of the cylinder
h is the height of the cylinder
we have
[tex]V=30\ ft^3[/tex]
[tex]r=2\ ft[/tex]
[tex]\pi =3.14[/tex]
substitute
[tex]30=(3.14)(2^{2})h[/tex]
Solve for h
[tex]30=(3.14)(4)h[/tex]
[tex]h=30/12.56[/tex]
[tex]h=2.39\ ft[/tex]
