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 pl. (1 point)
452 16 square centimeters
1,356 48 square centimeters
339 12 square centimeters
197.82 square centimeters
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.
