Answer:

[tex]h=1.59 inch[/tex]

Step-by-step explanation:

Volume of the cylinder=[tex]45inch^3[/tex]

Radius(r) of the cylinder=3 inch

To find height(h) of the cylinder:

Volume of a cylinder=[tex]\pi *r^2*h[/tex]

    [tex]45=3.14*3*3*h[/tex]

    [tex]45=3.14*9*h\\\\45=28.26*h[/tex]

     [tex]h=45/28.26[/tex]

      [tex]h=1.59 inch[/tex]

The height of the cylinder is : [tex]h=1.59 inch[/tex]
