How do you find the circumference of a cylinder with a 7 m radius?

The circumference of a cylinder works the same way as the circumference of a circle, as both faces of a cylinder are circles.

The circumference of a circle can be found with the formula  where r is the radius.

If you can enter the answer in terms of pi, I would suggest you do that. If not, just multiply by 3.14.

Hope this helps!
