The surface area of a cone can be calculated using the formula:
A = πr(r + l)
Where r is the radius of the cone and l is the slant height.
Plugging in the given values:
A = 3.14(10)(10 + 15)
A = 3.14(10)(25)
A = 3.14(250)
A = 785 square inches
Therefore, the surface area of the cone is 785 square inches.
