The formula to calculate the surface area of a cone is given by:
Surface Area = π * r * (r + l)
where r is the radius of the base of the cone and l is the slant height.
Plugging in the values:
Surface Area = 3.14 * 10 * (10 + 15)
Surface Area = 3.14 * 10 * 25
Surface Area = 785 in²
Therefore, the surface area of the cone is 785 square inches.
