Question

The volume of a cylinder is 2561 in. and the height of the cylinder is 1 in. What is the
radius of the cylinder?​

Answer 1

Answer:

$r=\sqrt{815.61}$ inch

Step-by-step explanation:

Volume of the cylinder= 2561 cubic inches

Height=1 inch

Radius=?

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

Putting the values in the formula:

      $2561=3.14*r^2*1$

          $2561=3.14*r^2$

       Dividing 3.14 both sides

          $2561/3.14=r^2\\\\r^2=815.61$

         $r=\sqrt{815.61}$

So, radius 'r' is  $r=\sqrt{815.61}$ inch
