The lateral surface area of a cone-shaped megaphone can be found using the formula:
Lateral surface area = π × radius × slant height
Given that the radius is 15 centimeters and the slant height is 20 centimeters, we can substitute these values into the formula:
Lateral surface area = 3.14 × 15 × 20
Lateral surface area = 942 square centimeters
Therefore, the correct answer is 942 square centimeters.
