The formula for working out the circumference is 2pi x radius, aka pi diameter.
The radius is 6 so times this by 2 and then pi. The answer would be:
(6 x 2) x pi = 12 x pi = 37.69911184.
Pay attention in maths lessons next time! ;) Hope this helps.

A circle with a radius of 6 mm has a circumference of 37.7 mm
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
It needs to be more specific. is 6 the diameter or radius of a circle?
The radius is 1/2 of the circumference.
The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.
