\huge\fbox{Hi~there!}

Remember the formula for the circumference of a circle:


\rm{C=2\pi r

We know that the radius of this circle is 7 in. So, let's plug it into the formula:


\huge\mathrm{C=2\pi (7) }


\rm{C=14\pi

C≈44 in (Answer)

Hope you find it helpful.

Feel free to ask if you have any doubts.
