When shopping trolleys are inserted into each other, there is a certain amount of "give", meaning that one trolley is not facing exactly the same direction as the next. Point each trolley to the right of the next and this allows you to bend a long line of trolleys into an arc. There will be a minimum radius that the arc can have limited by the amount of "give". The picture shows a large radius circle, so it's entirely possible, I would say. You just need enough trolleys and insert the front of the last trolley into the back of the first.
