To find the surface area of a cone, we use the formula:
Surface Area = π * r * (r + l)
where r is the radius and l is the slant height.
In this case, the radius is 6 centimeters and the slant height is 18 centimeters.
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.
A spyglass in the shape of a cone has a slant height of 18 centimeters and a radius of 6 centimeters. What is the surface area of the spyglass? Use 3.14 for pi.(1 point)
