Question

Three(cylindrical) steel drums are put together and a steel band is wrapped tightly around the three drums. If the radius of each drum is 2 feet, what is the length of the steel band? (The view of the drums below is from the top, or end of the drums.)

The three drums are in a triangular shape. One drum is on top and two are on bottom. This is by looking at them from the top like a top view.

Thanks!
