To find the surface area of the cone peak, we need to calculate the lateral area of the cone, which is given by the formula LA = π * r * l, where r is the radius of the base and l is the slant height.
Since the diameter of the cone is 14 inches, the radius is half of that, so r = 14/2 = 7 inches.
The slant height is given as 20 inches.
Now we can plug these values into the formula: LA = 3.14 * 7 * 20
LA ≈ 439.2 square inches.
Therefore, the surface area of the cone peak is approximately 439.2 square inches.
