Question 312795: c= r=4 units not for sure how to do it

You can put this solution on YOUR website!
Your question is not clear. Are you giving that the radius is 4 units, and you want to find the Circumference C??? If so, the formula for Circumference is
C=+2%2Api%2A+r
C+=+2%2A+pi+%2A+4
C+=+8%2Api units.
