First, we need to convert the measurements to the same units. Since the diameter is given in feet, we need to convert the slant height to feet as well.
Since the slant height is given in feet, the length of the radius is 12 feet / 2 = <<12/2=6>>6 feet.
Now we can use the formula to calculate the surface area of a cone:
Surface Area = π * r * (r + l)
where r is the radius and l is the slant height.
Surface Area = 3.14 * 6 feet * (6 feet + 14 feet)
Surface Area = 3.14 * 6 feet * 20 feet
Surface Area = 376.8 square feet
Since we need to round to the nearest tenth, the surface area of the cone is approximately 376.8 square meters.
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.
