Algebra 2 - do not guess! explain your answer : )

how far does the barnacle travel in one revolution of the water wheel?

just the last question in the picture ^^ i got the other two! this question is very confusing and i forget how to do it so some would be great : ,)

will report any random guesses**

The travel of the barnacle would be the circumference of the circle.

Circumference formula is 2 x PI x r

Circumference  = 2 x PI x 1m

= 2 x PI

If you use 3.14 for PI the circumference is 2 x 3.14 = 6.28 m.

Round the answer as needed.
