circle = is 6.28 
π=3.14

Answer:  [tex]r=\dfrac{C}{2\pi}[/tex], where C is the circumference of the circle.

Step-by-step explanation:

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

[tex]C=2\pi r[/tex], where r is the radius of the circle.

To find the expression for r , we divide [tex]2\pi[/tex] on the both sides , we get

[tex]\dfrac{C}{2\pi}=r[/tex]

OR

[tex]r=\dfrac{C}{2\pi}[/tex]

Hence, the expression for r will be:-

 [tex]r=\dfrac{C}{2\pi}[/tex], where C is the circumference of the circle.
