A coneshaped megaphone has a radius of 15 centimeters and a slant height of 20 centimetersA megaphone has an open bottomWhat is the lateral surface area of the megaphone, in square centimeters? Use 3.14 for pi.
The lateral surface area of a cone can be calculated using the formula:
Lateral surface area = πrℓ
where r is the radius and â„“ is the slant height.
Given that the radius of the megaphone is 15 centimeters and the slant height is 20 centimeters, we can plug 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.
