Question

What’s the circumference, to this problem ?

Answer 1

The formula to get the circumference of a circle is
`C=2*\pi * r` but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this
`C=d*\pi`.

We can then input the value and we get that
`C=1*\pi` which then just narrows down to
`C=3.142`.

Hope this helps! Let me know if you have any questions
