To find the lateral surface area of the megaphone, we need to find the area of the curved surface.
The formula for the lateral surface area of a cone is given by:
Lateral Surface Area = π * radius * slant height
Plugging in the values we have:
Lateral Surface Area = 3.14 * 15 cm * 20 cm
Lateral Surface Area = 942 square centimeters
Therefore, the correct answer is: 942 square centimeters
