Question

Find the circumference in terms of pic if the diameter is 2.5

Answer 1

`C=2.5\pi`

Explanation:

Radius is always half of the diameter so,
`(2.5)/(2) \\` is equal to
`1.25`.

The Formula for Circumference is
`C=2\pi r`

Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be:
`C=2\pi (1.25)`

Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)

So our answer is going to be
`C=2.5\pi`
