Question

Hello can u assit me please #Calculate the surface area.3

Answer 1

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.
