Final answer:

The surface area of the cone is approximately 348.51 square units.

Step-by-step explanation:

To find the surface area of a cone, you need to know the radius (r) and the height (h). The formula for the surface area of a cone is:

A = πr(r + √(r² + h²))

Substituting in the given values:

A = 3.14(6(6 + √(6² + 11²)))

A = 3.14(6(6 + √(36 + 121)))

A = 3.14(6(6 + √(157)))

A = 3.14(6(6 + 12.53))

A = 3.14(6(18.53))

A = 3.14(111.18)

A ≈ 348.51

Therefore, the surface area of the cone is approximately 348.51 square units.
