Answer:
$r=(C)/(2\pi)$ , where C is the circumference of the circle.

Explanation:

We know that the formula to calculate the circumference of the circle is given by :-

$C=2\pi r$ , where r is the radius of the circle.

To find the expression for r , we divide
$2\pi$ on the both sides , we get

$(C)/(2\pi)=r$

OR

$r=(C)/(2\pi)$

Hence, the expression for r will be:-

$r=(C)/(2\pi)$ , where C is the circumference of the circle.
