What is the exact circumference of a circle with a radius of 12 inches?

Anestetic [448]

We can get the circumference of any circle in terms of the radius with this formula. C = 2 $\pi$ r.

Where r is the radius of the circle.

And we will use 3.14 for $\pi$ .

Plug in all the values.

C = 2 * 3.14 * 2

C = 12.56

So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
