Question

What’s the circumference, to this problem ?

Answer 1

Answer:

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 $C=5*\pi$ which then just narrows down to $C=15.708$.

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