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