Question

The volume of a cylinder is 45 in 3. if the radius is 3in, whats the height?

Answer 1

Answer:

$h=1.59 inch$

Step-by-step explanation:

Volume of the cylinder=$45inch^3$

Radius(r) of the cylinder=3 inch

To find height(h) of the cylinder:

Volume of a cylinder=$\pi *r^2*h$

    $45=3.14*3*3*h$

    $45=3.14*9*h\\\\45=28.26*h$

     $h=45/28.26$

      $h=1.59 inch$

The height of the cylinder is : $h=1.59 inch$
