Perimeter

A rolling pin has a diameter of d = 5 inches.

We know the length of the circumference that encircles it is given by

P = π · d

Then

P = π · 5

P = 5π

It it made 35 rotations then it traveled the length of the circumference that encircles it. That is:

35 · 5π ≅ 549. 78 in

Answer: it traveled 549. 78 in
