Answer:

Option A: c/12 is the correct answer.

Explanation:

Given that:

We use C to represent the circumference of a circle and in the formula

C = πd

Diameter of circle is 12 inches.

Putting d = 12 in the given formula

c = 12π

Dividing both sides by 12


(c)/(12)=(12 \pi)/(12)\\\pi = (c)/(12)

Hence,

Option A: c/12 is the correct answer.
