Question

We use C to represent the circumference of a circle and in the formula c=nd. The diameter of a circle is 12 inches. Solve the equation for pi (get pi by itself). Which expression best represents the value of circle?

A.c/12 B.12/c C.c/6 D.6/c

Answer 1

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.
