ELI5: Explain Like I'm 5

Cone

Hey there kiddo! A cone is a really cool shape that looks like a pointy hat or ice cream cone! It's made up of a flat circle on the bottom and a pointed tip at the top, and everything in between is rounded.

Just like how a cake can be sliced into pieces, a cone can also be sliced! But instead of getting a piece of cake, you get a shape that looks like a triangle! That triangle shape is called a "sector" and it's really useful for calculating things like how much ice cream can fit in a cone or how much paint you need to cover a cone-shaped object.

So, if you ever see an ice cream cone or a traffic cone, just remember that it's a cone shape! Cool, huh?
