To find the surface area of the cone, we need to calculate the lateral surface area.
The lateral surface area of a cone is given by the formula: LSA = π * r * l, where r is the radius and l is the slant height.
Given that the diameter (d) of the cone is 14 inches, the radius (r) can be calculated by dividing the diameter by 2: r = d/2 = 14/2 = 7 inches.
Now, we can substitute the values into the formula:
LSA = 3.14 * 7 * 20
= 439.2 in² (rounded to the nearest hundred)
Therefore, the surface area of the cone is approximately 439 square inches.
