What is the surface area, in square centimeters, of a cone with a diameter of 12 feet and a slant height of 14 feet? Use 3.14 for pi and round to the nearest tenth, if necessary.(1 point)
The radius of the cone is half of the diameter, so it is 12/2 = 6 feet.
The formula for the surface area of the cone is A = π * r * (r + l), where r is the radius and l is the slant height.
Substituting the values into the formula, we get A = 3.14 * 6 * (6 + 14) = 3.14 * 6 * 20 = 3.14 * 120 = 376.8 square centimeters.
Rounding to the nearest tenth, the surface area is 376.8 square centimeters. Answer: \boxed{376.8}.
