Answer:A) r= C over 2 pie

Step-by-step explanation:

Given: The circumference of a circle can be found using the [tex]C=2\pi r[/tex]

To solve the above equation for radius of the circle 'r', first divide [tex]2\pi[/tex] on both sides of the equation, we get

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

Hence, the formula to calculate radius 'r' is the circle will be :  [tex]r=\dfrac{C}{2\pi}[/tex]
