Speak Louder!

Geometry Level 2

You're making a megaphone by wrapping a piece of paper up as a simple cone and then cutting it at half of its height. The 2 new circular bases are parallel and left open at both ends for the air to flow through.

If this megaphone has a height of 24 cm. with a radius of 14 cm. at its bigger base, find its lateral surface area in \(\text{cm}^2\).

If your answer is in a form of \(\pi\times A\), then submit \(A\) as your answer.
