To calculate the height of the cylinder given its surface area, we can use the formula for the surface area \( S \) of a cylinder, which is given by:

\[ S = 2\pi r(h + r) \]

Where:

  • \( S \) is the surface area,
  • \( r \) is the radius,
  • \( h \) is the height.

Given that the surface area \( S \) is 3,106.716 square feet, we can rearrange the formula to solve for height \( h \):

\[ 3,106.716 = 2\pi r(h + r) \]

However, to find the height \( h \), we need either the radius \( r \) or more information relating to it.

Assuming we do not have a specific radius, we need to derive an expression for \( h \) in terms of \( r \):

  1. Rearranging the equation for \( h \):

\[ h = \frac{3,106.716}{2\pi r} - r \]

Substituting \( \pi \approx 3.14 \):

\[ h = \frac{3,106.716}{2 \times 3.14 r} - r \]

\[ h = \frac{3,106.716}{6.28 r} - r \]

If you know the radius \( r \), you can substitute it into the equation above to find the height \( h \).

Please provide the radius \( r \) of the cylinder so that we can calculate the height accurately. If no radius is given and you need a specific height using a particular radius, please specify that radius.
