Answer:
[tex]2\pi[/tex]
Step-by-step explanation:
We are asked to find the expression that is multiplied to r to get the formula for the circumference of a circle.
We know that circumference of circle is [tex]2\pi r[/tex].
We will divide [tex]2\pi r[/tex] by r to get our required expression as:
[tex]\frac{2\pi r}{r}[/tex]
Upon cancelling out r, we will get:
[tex]2\pi[/tex]
Therefore, [tex]2\pi[/tex] is multiplied by r, to get the formula for the circumference of a circle.
