To find the lateral surface area of the cone-shaped megaphone, we need to find the curved surface area of the cone. The formula for the curved surface area of a cone is:
Curved Surface Area = π × radius × slant height
In this case, the radius is 15 centimeters and the slant height is 20 centimeters. Plugging in these values into the formula, we get:
Curved Surface Area = 3.14 × 15 × 20
Curved Surface Area = 942 square centimeters
Therefore, the lateral surface area of the megaphone is 942 square centimeters.
Curved Surface Area = π × radius × slant height
In this case, the radius is 15 centimeters and the slant height is 20 centimeters. Plugging in these values into the formula, we get:

Curved Surface Area = 942 square centimeters
Therefore, the lateral surface area of the megaphone is 942 square centimeters.
