Answer :
Answer
[tex]C=2.5\pi[/tex]
Step-by-step explanation:
Radius is always half of the diameter so, [tex]\frac{2.5}{2} \\[/tex] is equal to [tex]1.25[/tex].
The Formula for Circumference is [tex]C=2\pi r[/tex]
Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be: [tex]C=2\pi (1.25)[/tex]
Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)
So our answer is going to be [tex]C=2.5\pi[/tex]
Hope this helped and answers your question! Have a great rest of your day/night!
