Explanation:

Step1: Recall the formula for the surface area of a cone

The formula for the surface area of a cone is \(S=\pi r(r + l)\), where \(r\) is the radius and \(l\) is the slant height.

Step2: Substitute the given values into the formula

Given \(r = 5\) meters and \(l=8\) meters, and \(\pi = 3.14\).

Step3: Calculate the result

First, \(5\times13 = 65\). Then \(3.14\times65=204.1\)

Answer:

\(204.1\)
