Answer 1

Answer:

The radius of the cylinder is  $r=6$  meters.

Step-by-step explanation:

To determine:

What is radius?

Information Fetching and Solution Steps:

The volume of the cylinder = 1,921.68 cubic meters

$\pi \approx 3.14$

The height = 17 m

As the formula of the volume of the cylinder

                                    $V=\:\pi \:r^{2} \:h$

The radius can be determine as

                                   $r^{2} \:=\:\frac{V}{\pi \:h}$

                                     $r=\sqrt{\frac{V}{\pi \:\:h}}$

                                      $\:r=\sqrt{\frac{1921.68}{\left(3.14\right)\:\left(17\right)}}$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

                                      $r=\sqrt{\frac{1921.68}{3.14\cdot \:17}}$

$\mathrm{Multiply\:the\:numbers:}\:3.14\cdot \:17=53.38$

                                       $r=6$  meters

Therefore, the radius of the cylinder is  $r=6$  meters.
