### Solution:

We have a circle of radius  .
Since we already know that the circumference of a circle is equal to  ,
By deducting the radius from the circumference and equating the result to the supplied variables, we create an equation.

In the Left-Hand Side of the equation, take   common.

Divide both sides of the equation by

Remove the identical terms from the denominator and numerator on both sides of the equation.

Now we know that the length of diameter of the circle is twice the length of the radius of the circle.
Diameter of the circle with radius
Diameter of the circle with radius
Diameter of the circle with radius '   ' is
Hence, correct option is ‘2’
