Answer:

C≈47.12, or 47.1

Step-by-step explanation:

To find the circumference you just use the formula C=2[tex]\pi[/tex]r.

The radius of your circle is 7.5 which is half of 15, now multiply 2[tex]\pi[/tex](7.5) which gives you your answer!

An even easier way to do this is to use the other formula C=d[tex]\pi[/tex],

Just multiply your diameter (which is what was given to you) by pi and you also get your answer!

Hope this helps! :)
