This design arrangement is very common : there is one Driven Pulley.
The belt becomes driven by the Driven-Pulley. The other Pulleys become driven, via the Belt.

In this example, the sketch-loop has two Arcs and two Lines.
It is easier to Add the Arc, then Hover+Drag the Line to merge it with the centre of the Arc.
The exact radius of the Arc is not important. MechDesigner will add a Pulley with an integer number-of-teeth and pitch to give radius that is near to the dimension. You can edit the number-of-teeth and tooth pitch later, of course.
