The surface area of a cone can be found using the formula:
Surface Area = πr(r + slant height)
First, we need to find the radius of the cone. The diameter is given as 14 inches, so the radius would be half of that, which is 7 inches.
Next, we can substitute the values into the formula:
Surface Area = 3.14 * 7 * (7 + 20)
Surface Area = 3.14 * 7 * 27
Surface Area = 592.86 square inches
Rounded to the nearest hundredth, the surface area of the cone peak is approximately 592.86 square inches.
