Answer:
[tex]C = \pi (2x -2)[/tex]
Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula [tex]C = \pi d[/tex].
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.
[tex]C = \pi (2x -2)[/tex]
