Yes, you are correct! The surface area of a cone is given by the formula SA = πr² + πrl, where r is the radius of the base and l is the slant height of the cone. Since the diameter of the base is given as 17 inches, the radius r is half of that, or 8.5 inches. However, to calculate the surface area using the formula above, we also need to know the slant height l of the cone.
