<h2>The height of cylinder is 11.8 meters</h2>
<em><u>Solution: </u></em>
<em><u> The volume of cylinder is given as:</u></em>
Where,
r is the radius and h is the height of cylinder
From given,
V = 95 cubic meters
r = 1.6 meters
h = ?
<em><u> Substituting the values we get,</u></em>
Thus height of cylinder is 11.8 meters
