Question

Find the circumference in terms of pic if the diameter is 2.5

Answer 1

Answer

$C=2.5\pi$

Step-by-step explanation:

Radius is always half of the diameter so, $\frac{2.5}{2}$ is equal to $1.25$.

The Formula for Circumference is $C=2\pi r$

Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be: $C=2\pi (1.25)$

Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)

So our answer is going to be $C=2.5\pi$
