What is the surface area in square centimeters of a cone with a Demeter of 12 ft and a slant height of 14 ft used 3.14 for pi and rum to the nearest tenth of necessary
First, we need to calculate the radius of the cone using the diameter given. The diameter is 12 ft, so the radius would be half of that, 6 ft.
Next, we can calculate the lateral surface area of the cone using the slant height and the radius. The formula for the lateral surface area of a cone is given by:
Lateral surface area = π * radius * slant height
Substituting the values we have:
Lateral surface area = 3.14 * 6 ft * 14 ft = 263.52 ft^2
Therefore, the lateral surface area of the cone is approximately 263.5 square feet.
