The lateral surface area of a cone can be found using the formula: LSA = π * r * l, where r is the radius and l is the slant height.
In this case, the radius (r) is 15 centimeters and the slant height (l) is 20 centimeters.
LSA = 3.14 * 15 * 20
LSA = 942 square centimeters
Therefore, the lateral surface area of the megaphone is 942 square centimeters.
A cone-shaped megaphone has a radius of 15 centimeters and a slant height of 20 centimeters. A megaphone has an open bottom. What is the lateral surface area of the megaphone, in square centimeters? Use 3.14 for pi.(1 point)
