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)

1 answer

The radius of the cone is half the diameter, so it is 12/2 = 6 feet.
The lateral surface area of the cone can be found using the formula:

Lateral surface area = π * r * slant height

Lateral surface area = 3.14 * 6 * 14
Lateral surface area ≈ 263.52

Rounding to the nearest tenth, the surface area of the cone is approximately 263.5 square centimeters.
