Thank you Ms. Sue. Sorry I didn't tell you we're just learning that pi=3 for now. It made everything complicated for you to check if my answers were correct. :P

But what is this formula usually used for?Diameter=Circumference/π?

Is it used to find the diameter of something?

That's ok. I'm glad we've straightened out that problem.

The formula is usually written as
Circumference = pi * diameter

But if we want to find the diameter, we can switch it around to
Diameter=Circumference/π

is that used to find the radius? And is it
usually written as Circumference=2πr?

• Math -

Yes.

Okay, thank you again! :D
