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

And the formula Radius=Circumference/2π

is that used to find the radius? And is it

usually written as Circumference=2πr?
