Squirrelflight: Okay, apprentices, today we have a very important lesson!

Dewpaw: What's it about?

Squirrelflight: CIRCLES!!!

Amberpaw: Circles?

Snowpaw: What is there to learn? They're round, called circles and nobody can draw a perfect one. BAM.

Squirrelflight: D: Why you steal my thunder?

Snowpaw: ...You seriously were planning to waste out time teaching material WE ALREADY KNOW?!?!

Squirrelflight: The best warriors learned about circles. *leans in closer* I heard Bramblestar didn't learn about them.

Apprentices: *gasps*

Squirrelflight: Don't leave just yet! *pulls out chart from nowhere* I got a backup plan!

Apprentices: *groan*

Squirrelflight: So there is a radius, diameter, circumference, and an area. These also apply to squares and cylinders and stuff. You get a radius by dividing the diameter in half, circumference by the diameter times 3.14, also known as pi, and the area by the radius squared multiplied by 3.14, or pi.

Amberpaw: How do you get the diameter?

Squirrelflight: Measure it. *gives them a chart, circles, and a ruler* Have fun, get this back by tomorrow! *pushes them away*

NEXT MORNING

(IN THE NINJA MAN'S LAYER)

(JK)

Squirrelflight: *checks Amberpaw's and Dewpaw's homework* Nicely done.

Snowpaw: *has no homework*

Squirrelflight: Child, you better explain yo-self.

Snowpaw: Squares are better.

Squirrelflight: ...

Snowpaw: I mean, they have four sides and everything.

Squirrelflight: ...

Dewpaw: He's not wrong.

A/N: Ayy chapter 100. :D Am I really getting that old, guys?
