"circumference" is a distance; it's the distance around the outside of a circle.

The formula for circumference is C=2 pi r, where pi =3.14 and r is the radius of the circle.

Here we are GIVEN the circumference. but  no the radius, r.

So we need to solve the formula C = 2 pi r for r.

If  C= 2 pi r,

divide both sides by 2 pi.  You'll have "r" on the right side.
