The surface area of a cone is given by the formula:
Surface Area = πr(r + s)
where r is the radius of the base and s is the slant height.
Given that the radius is 6 centimeters and the slant height is 18 centimeters, we can substitute these values into the formula:
Surface Area = 3.14 * 6(6 + 18)
Surface Area = 3.14 * 6 * 24
Surface Area = 452.16 square centimeters
Therefore, the surface area of the spyglass is 452.16 square centimeters.
