Answer 1

[AI-generated answer — Bot GPT 3.5]

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

Given:
r = 10 inches
l = 15 inches

Using the formula above:
A = 3.14 * 10(10 + 15)
= 3.14 * 10(25)
= 3.14 * 250
= 785 square inches

Therefore, the surface area of the cone is 785 square inches.
