The formula for finding the surface area of a cone is A = πr(r + s), where r is the radius of the base and s is the slant height of the cone.

Given that the radius of the cone is 7 inches and the slant height is 8 inches, we can plug these values into the formula:

A = π(7)(7 + 8)
A = π(7)(15)
A = 105π

To find the surface area to the nearest whole unit, we need to substitute 3.14 for π and calculate the value:

A ≈ 105 * 3.14
A ≈ 329.7 in^2

Rounded to the nearest whole unit, the surface area of the cone is 330 in^2.

Therefore, the answer is not provided in this multiple-choice question.
But what’s the correct answer A B C or D
Based on the question and the calculations provided, none of the provided answer choices (A, B, C, D) match the correct surface area of the cone calculated to be approximately 330 in^2. Therefore, the correct answer is not listed among the choices given.
