The surface area of a cone can be calculated using the formula:
Surface Area = π * radius * slant height + π * radius^2
Plugging in the values given:
Surface Area = 3.14 * 10 * 15 + 3.14 * 10^2
Surface Area = 471 + 314
Surface Area = 785 square inches
Therefore, the correct answer is 785 square inches.
