@Shadow e.e

Nicole:

It has to be written please

Shadow:

\[C = 2 \pi r\]

Nicole:

But how would we use a model...I think that is also part of the question

Shadow:

Is this MC, or is there more information?

Nicole:

no this is it

Nicole:

How would you use a model to determine the approximate formula for the circumference of a circle with a diameter of 6 cm, and connect the model to the actual formula?

Nicole:

?

@dude

Shadow:

Since the circumference of a circle divided by it's diameter is a value close to pi, we get. \[\pi = \frac{ C }{ d }\] This is where the formula for the circumference of a circle is derived from. Honestly though, this question makes no sense. I'm in AP English and all my friends are suggesting you skip this xD

Nicole:

The circumference of a circle with the diameter of 3 cm is 9.42 cm. What is the ratio of the circumference to the diameter?
