The formula for the lateral surface area of a cone is given by LSA = π * r * l, where r is the radius and l is the slant height.
Plugging in the given values, we have LSA = 3.14 * 15 cm * 20 cm = 942 square centimeters.
Therefore, the lateral surface area of the megaphone is 942 square centimeters.
