The formula to calculate the surface area of a cone is:
Surface Area = π * r * s
where r is the radius of the base and s is the slant height.
Given that the diameter of the cone is 14 inches, the radius (r) is half of that, which is 7 inches.
Using the given slant height (s) of 20 inches, the surface area can be calculated as follows:
Surface Area = 3.14 * 7 * 20 = 439.6 square inches
Rounding to the nearest hundredth, the surface area of the cone peak is 439.6 square inches.

Apologies for the previously incorrect calculation.
To calculate the surface area of the cone, we need to find the slant height (s) and the radius (r) of the base.
Given that the diameter of the cone is 14 inches, the radius (r) is half of that, which is 7 inches.
Using the given slant height (s) of 20 inches, the surface area can be calculated as follows:
Surface Area = π * r * s
Surface Area = 3.14 * 7 * 20
Surface Area = 439.6 square inches
Rounding to the nearest hundredth, the surface area of the cone peak is approximately 439.6 square inches.
