The slant height of the cone

$\text{slant height = 22.4mi}$

Radius of the base of cone

$\text{ radius = 10 mi}$

The surface area of cone is:

$\text{ Surface are of cone = }\Pi radius\text{ }* slant\text{ height+}\Pi radius^2$

Substitute the value and simplify

$\begin{gathered} \text{ Surface area of cone = }(22)/(7)*10*22.4+(22)/(7)*10*10 \\ \text{Surface area of cone = 1017.9mi}^2 \end{gathered}$

Answer: D) 1017.9 mi^2
