The formula to calculate the surface area of a cone is given to be:


A=πrl+πr^2

where l is the slant height and r is the radius.

The following parameters are provided in the question:


\begin{gathered} r=6\text{ yd.} \\ l=13.4\text{ yd.} \end{gathered}

Therefore, the surface area is calculated to be:


\begin{gathered} A=(\pi*6*13.4)+(\pi*6^2) \\ A\approx365.7\text{ yd}^2 \end{gathered}

The surface area is 365.7 square yards.
