The surface area of a cone is given by the formula:

Surface Area = πr(r + s)

Given that the diameter of the cone is 6m, the radius (r) is half of that, so r = 3m.

Surface Area = π * 3 * (3 + 9.5)
Surface Area = π * 3 * 12.5
Surface Area = 37.5π

Rounded to the nearest tenth, the surface area is approximately 117.8 m².

Therefore, the correct answer is:

117.8 m²
