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 microphone, in square centimeters? Use 3.14 for pi
The lateral surface area of a cone is given by the formula LSA = πrl, where r is the radius and l is the slant height.
Given that the radius is 15 centimeters and the slant height is 20 centimeters, we can substitute these values into the formula to find the lateral surface area.
LSA = π * 15 * 20
LSA = 300π
Approximating π to 3.14, we can calculate the lateral surface area:
LSA ≈ 300 * 3.14
LSA ≈ 942 cm^2
Therefore, the lateral surface area of the megaphone is approximately 942 square centimeters.
